DB2 users and groups
- by Arun Srini
Just want to know everyone's experience and take on managing users/authentication on a multi-node db2 cluster with users groups. I have 17 apps in production (project based company, only 2 online apps), and some 30 users with 7 groups.
prodsel - group that has select privilege on all tables
produpdt - update group on selective tables (as required by the apps)
proddel - delete
prodins - insert permissions for the group
Now what my company does is when an app uses certain user (called app1user), and needs select and insert privilege on a table, they
1. grant select and insert for prodsel, prodins respectively
2. add the user under those two groups...
now this creates one to many relationship between user and privileges, and this app1user also gets select on other tables granted for the prodsel group. I know this is wrong. Before I explain, I need to know how this is done elsewhere.
Please share your experiences, even if you use other Databases that uses OS level authentication.
