  • Must have local user to authenticate Samba to AD?

    - by Phil
    I've got a CentOS 5.3 server with Samba running. I've joined this server to my domain in the hopes of allowing AD users some access to my Samba shares. I've found that this works, but only as long as the AD username that I'm trying to authenticate with is also a local user on the server. In other words, if I'm trying to access a share, and try to authenticate with the AD username "joe", I get errors unless I create a user named 'joe' on the server. I don't have to create a matching password or anything....the local user's password is always blank, so I do know that the authentication is actually happening against the AD. Here's my smb.conf file: [global] workgroup = <mydomain> server string = <snip> netbios name = HOME security = ADS realm = <mydomain.com> password server = <snip> auth methods = winbind log level = 1 log file = /var/log/samba/%m.log [amore] path = /var/www/amore browseable = yes writable = yes valid users = DOMAIN\user1 DOMAIN\user2 DOMAIN\user3 DOMAIN\user4 I would assume that my kerberos settings are fine, as I've joined the domain and can use wbinfo to see users and groups. However, I can provide that info if necessary. Anyone have any ideas?

  • Is it logical that file system acls would be corrupted in a way that adds permission for another user?

    - by wilbbe01
    I was having issues on a shared hosting provider with the host's web server instance not serving some files. I asked the companies support about the issue and they responded with the results of getfacl on my home directory, and added the necessary line to allow their web server to obtain the necessary permissions. All is working happily now, but I noticed a line in the getfacl that was for what appeared to be another username to which I had no relation. I asked them about this and their response was that it was likely some minor corruption and that I could remove the unwanted line with the setfacl -x option. I know I never added the user to my home directory, and I also find it weird that that could truly happen due to corruption. So now that it is fixed I'm a little bit weary of whether or not they were trying to cover up a problem they accidentally gave someone permissions to my account, or if this kind of thing can really be corrupted in that way. Especially when that user is a real user on the same server. Any thoughts? Thanks.

  • Linux SFTP and many local user accounts, limits with mount --bind?

    - by user123428
    I am in the process of building a solution to handle many developers (possibly hundreds) to work on their files via sftp, each one Jailed in their home directory. For our particular needs, we have a samba mount point that contains all of the users home directories. I have started developing the following solution and hit some walls: - I have configured a Ubuntu Lucid Server as sftp server. - In order to jail the user in their home directory (without allowing them the browse a directory up and seeing all the other users folders) I am using mount --bind and not a symbolic link (also some ftp clients don't really work with sym links). - The user accounts are local unix user accounts on the sftp server (not using a directory service or anything) that have an empty home folder created on the local machine, then I use mount --bind to bind the empty folder to the actual users home directory on the samba share. With this solution I am hitting a couple of problems, in the case of a server reboot, all the mount --binds are lost because they are not written in fstab. Then I have read somewhere that the maximum amount of entries in fstab are 400 (which does not really help us). I have thought of a solution of writing something that stores the mounts in a text file as a backup and on server reboot, run the script that re mounts. I am just really unsure about this whole process and was wondering if anyone has any insight on possibly a better solution for SFTP? (not FTP)

  • Can't login to Windows server 2008 (as any user, not even locally, not in safe mode but I have right credentials)

    - by Saix
    Just from nowhere I can't login to my Windows server 2008 machine. All the services like FTP server or webserver (which I'm actually not using, just remote desktop and FTP) are running. Whatever credentials I try (even/especialy administrator), it always says Unknown Username or bad password. I have already tried hard turn off/on and safe mode without luck. Also I already tried type in login name as SERVER NAME\user or Workgroup\user (every case sensitive scenario), still says I have wrong login. Usually we are using remote desktop to access the machine but local access over KVM doesn't work either. Now I'm lock out of any control or any way to do something. There's just logon screen preceding by ctrl+alt+del to login alert. Without me able to login I can't actually try to fix anything. Can't find much more on Internet except the SERVER NAME\user thing. Reinstall would be the last resort but I can't let things this way for much longer anyway. This server is vital. If it would be any help, I think automatic Windows updates are turned off and there were no updates or newly installed software for last couple years and just few soft restarts, non of them recently. It happened during it's runtime while all other services were still up and running, so this couldn't be just some Windows nasty screw up during boot or something. What could have possibly changed? What are my options now?

  • How to get rid of messages addressed to not existing subdomains?

    - by user71061
    Hi! I have small problem with my sendmail server and need your little help :-) My situation is as follow: User mailboxes are placed on MS exchanege server and all mail to and from outside world are relayed trough my sendmail box. Exchange server ----- sendmail server ------ Internet My servers accept messages for one main domain (say, my.domain.com) and for few other domains (let we narrow it too just one, say my_other.domain.com). After configuring sendmail with showed bellow abbreviated sendmail.mc file, essentially everything works ok, but there is small problem. I want to reject messages addressed to not existing recipients as soon as possible (to avoid sending non delivery reports), so my sendmail server make LDAP queries to exchange server, validating every recipient address. This works well both domains but not for subdomains. Such subdomains do not exist, but someone (I'm mean those heated spamers :-) could try addresses like this: user@any_host.my.domain.com or user@any_host.my_other.domain.com and for those addresses results are as follows: Messages to user@sendmail_hostname.my.domain.com are rejected with error "Unknown user" (due to additional LDAPROUTE_DOMAIN line in my sendmail.mc file, and this is expected behaviour) Messages to user@any_other_hostname.my.domain.com are rejected with error "Relaying denied". Little strange to me, why this time the error is different, but still ok. After all message was rejected and I don't care very much what error code will be returned to sender (spamer). Messages to user@sendmail_hostname.my_other.domain.com and user@any_other_hostname.my_other.domain.com are rejected with error "Unknown user" but only when, there is no user@my_other.domain.com mailbox (on exchange server). If such mailbox exist, then all three addresses (i.e. user@my_other.domain.com, user@sendmail_hostname.my_other.domain.com and user@any_other_hostname.my_other.domain.com) will be accepted. (adding additional line LDAPROUTE_DOMAIN(my_sendmail_host.my_other.domain.com) to my sendmail.mc file don't change anything) My abbreviated sendmail.mc file is as follows (sendmail 8.14.3-5). Both domains are listed in /etc/mail/local-host-names file (FEATURE(use_cw_file) ): define(`_USE_ETC_MAIL_')dnl include(`/usr/share/sendmail/cf/m4/cf.m4')dnl OSTYPE(`debian')dnl DOMAIN(`debian-mta')dnl undefine(`confHOST_STATUS_DIRECTORY')dnl define(`confRUN_AS_USER',`smmta:smmsp')dnl FEATURE(`no_default_msa')dnl define(`confPRIVACY_FLAGS',`needmailhelo,needexpnhelo,needvrfyhelo,restrictqrun,restrictexpand,nobodyreturn,authwarnings')dnl FEATURE(`use_cw_file')dnl FEATURE(`access_db', , `skip')dnl FEATURE(`always_add_domain')dnl MASQUERADE_AS(`my.domain.com')dnl FEATURE(`allmasquerade')dnl FEATURE(`masquerade_envelope')dnl dnl define(`confLDAP_DEFAULT_SPEC',`-p 389 -h my_exchange_server.my.domain.com -b dc=my,dc=domain,dc=com')dnl dnl define(`ALIAS_FILE',`/etc/aliases,ldap:-k (&(|(objectclass=user)(objectclass=group))(proxyAddresses=smtp:%0)) -v mail')dnl FEATURE(`ldap_routing',, `ldap -1 -T<TMPF> -v mail -k proxyAddresses=SMTP:%0', `bounce')dnl LDAPROUTE_DOMAIN(`my.domain.com')dnl LDAPROUTE_DOMAIN(`my_other.domain.com ')dnl LDAPROUTE_DOMAIN(`my_sendmail_host.my.domain.com')dnl define(`confLDAP_DEFAULT_SPEC', `-p 389 -h "my_exchange_server.my.domain.com" -d "CN=sendmail,CN=Users,DC=my,DC=domain,DC=com" -M simple -P /etc/mail/ldap-secret -b "DC=my,DC=domain,DC=com"')dnl FEATURE(`nouucp',`reject')dnl undefine(`UUCP_RELAY')dnl undefine(`BITNET_RELAY')dnl define(`confTRY_NULL_MX_LIST',true)dnl define(`confDONT_PROBE_INTERFACES',true)dnl define(`MAIL_HUB',` my_exchange_server.my.domain.com.')dnl FEATURE(`stickyhost')dnl MAILER_DEFINITIONS MAILER(smtp)dnl Could someone more experienced with sendmail advice my how to reject messages to those unwanted subdomains?

  • ASP.NET MVC3 Custom Membership Provider - The membership provider name specified is invalid.

    - by David Lively
    I'm implementing a custom membership provider, and everything seems to go swimmingly until I create a MembershipUser object. At that point, I receive the error: The membership provider name specified is invalid. Parameter name: providerName In web.config the membership key is <membership defaultProvider="MembersProvider"> <providers> <clear/> <add name="MembersProvider" type="Members.Providers.MembersProvider" connectionStringName="ApplicationServices" enablePasswordRetrieval="false" enablePasswordReset="true" requiresQuestionAndAnswer="false" requiresUniqueEmail="false" maxInvalidPasswordAttempts="5" minRequiredPasswordLength="6" minRequiredNonalphanumericCharacters="0" passwordAttemptWindow="10" applicationName="DeviceDatabase" /> </providers> </membership> When creating the MembershipUser object from my custom User class: public static MembershipUser ToMembershipUser(User user) { MembershipUser member = new MembershipUser ("MembersProvider" , user.Name , user.Id , user.EmailAddress , user.PasswordQuestion , user.Comment , user.IsApproved , user.IsLockedOut , user.DateCreated , user.LastLoginDate ?? DateTime.MinValue , user.LastActivityDate ?? DateTime.MinValue , user.LastPasswordChangedDate ?? DateTime.MinValue , user.LastLockoutDate ?? DateTime.MinValue ); return member; } (I realize I could probably just inherit my User class from MembershipUser, but it's already part of an existing class hierarchy. I honestly think this is the first time I've encountered a legitimate need for for multiple inheritance!) My feeling is that the new MembershipUser(...) providerName parameter is supposed to match what's set in web.config, but, since they match already, I'm at a loss as to how to proceed. Is there a convenient way to get the name of the active membership provider in code? I'm starting to think that using the built-in membership system is overkill and more trouble than it's worth. Edit Not sure if it's relevant, but the custom membership provider class is in a class library, not the main WAP project. Update Here's the contents of the System.Web.Security.Membership.Provider object as show in the VS2010 command window: >eval System.Web.Security.Membership.Provider {Members.Providers.MembersProvider} [Members.Providers.MembersProvider]: {Members.Providers.MembersProvider} base {System.Configuration.Provider.ProviderBase}: {Members.Providers.MembersProvider} ApplicationName: null EnablePasswordReset: true EnablePasswordRetrieval: false MaxInvalidPasswordAttempts: 5 MinRequiredNonAlphanumericCharacters: 0 MinRequiredPasswordLength: 6 PasswordAttemptWindow: 10 PasswordFormat: Function evaluation was aborted.

  • JPA One To Many Relationship Persistence Bug

    - by Brian
    Hey folks, I've got a really weird problem with a bi-directional relationship in jpa (hibernate implementation). A User is based in one Region, and a Region can contain many Users. So...relationship is as follows: Region object: @OneToMany(mappedBy = "region", fetch = FetchType.LAZY, cascade = CascadeType.ALL) public Set<User> getUsers() { return users; } public void setUsers(Set<User> users) { this.users = users; } User object: @ManyToOne(cascade = {CascadeType.PERSIST, CascadeType.MERGE}, fetch = FetchType.EAGER) @JoinColumn(name = "region_fk") public Region getRegion() { return region; } public void setRegion(Region region) { this.region = region; } So, the relationship as you can see above is Lazy on the region side, ie, I don't want the region to eager load all the users. Therefore, I have the following code within my DAO layer to add a user to an existing user to an existing region object... public User setRegionForUser(String username, Long regionId){ Region r = (Region) this.get(Region.class, regionId); User u = (User) this.get(User.class, username); u.setRegion(r); Set<User> users = r.getUsers(); users.add(u); System.out.println("The number of users in the set is: "+users.size()); r.setUsers(users); this.update(r); return (User)this.update(u); } The problem is, when I run a little unit test to add 5 users to my region object, I see that the region.getUsers() set always stays stuck at 1 object...somehow the set isn't getting added to. My unit test code is as follows: public void setUp(){ System.out.println("calling setup method"); Region r = (Region)ManagerFactory.getCountryAndRegionManager().get(Region.class, Long.valueOf("2")); for(int i = 0; i<loop; i++){ User u = new User(); u.setUsername("username_"+i); ManagerFactory.getUserManager().update(u); ManagerFactory.getUserManager().setRegionForUser("username_"+i, Long.valueOf("2")); } } public void tearDown(){ System.out.println("calling teardown method"); for(int i = 0; i<loop; i++){ ManagerFactory.getUserManager().deleteUser("username_"+i); } } public void testGetUsersForRegion(){ Set<User> totalUsers = ManagerFactory.getCountryAndRegionManager().getUsersInRegion(Long.valueOf("2")); System.out.println("Expecting 5, got: "+totalUsers.size()); this.assertEquals(5, totalUsers.size()); } So the test keeps failing saying there is only 1 user instead of the expected 5. Any ideas what I'm doing wrong? thanks very much, Brian

  • Add save callback to a single ActiveRecord instance, is it possible?

    - by J. Pablo Fernández
    Is it possible to add a callback to a single ActiveRecord instance? As a further constraint this is to go on a library so I don't have control over the class (except to monkey-patch it). This is more or less what I want to do: def do_something_creazy message = Message.new message.on_save_call :do_even_more_crazy_stuff end def do_even_more_crazy_stuff(message) puts "Message #{message} has been saved!

  • TG2.1: Proper location to store a database session instance?

    - by Lee Olayvar
    I am using a custom database (MongoDB) with TG 2.1 and i am wondering where the proper place to store the PyMongo connection/database instances would be? Eg, at the moment they are getting created inside of my inherited instance of AppConfig. Is there a standard location to store this? Would shoving the variables into the project.model.__init__ be the best location, given that under SQLAlchemy, the database seems to commonly be retrieved via: from project.model import DBSession, metadata Anyway, just curious what the best practice is.

  • SQLAlchemy: a better way for update with declarative?

    - by hadrien
    I am a SQLAlchemy noob. Let's say I have an user table in declarative mode: class User(Base): __tablename__ = 'user' id = Column(u'id', Integer(), primary_key=True) name = Column(u'name', String(50)) When I know user's id without object loaded into session, I update such user like this: ex = update(User.__table__).where(User.id==123).values(name=u"Bob Marley") Session.execute(ex) I dislike using User.__table__, should I stop worrying with that? Is there a better way to do this? Thanx!

    Straightforward question - apologies if it is a duplicate, but I can't find the answer if so. I have a User model and a Submission model, like this: class Submission(models.Model): uploaded_by = models.ForeignKey('User') class User(models.Model): name = models.CharField(max_length=250 ) How can I show the number of Submissions made by each user in the template? I've tried {{ user.submission.count }}, like this: for user in users: {{ user.name }} ({{ user.submission.count }} submissions) but no luck...
