Hello,

I'm trying to look for users inside Active Directory through a LDAP query. Basically I'm searching for the user in this way:

Search DN: dc=mydomain, dc=com
Filter: (sAMAccountName=USER)  where USER is replaced with the provided username.

Now if USER is only the username without domain (for ex. "Joe") this works fine. However I receive them in the form (domain\username, for ex. "myDomain\Joe") and obviously the search fails.

I see two ways:

  • using a regex inside the Search Filter to discard the domain
  • using a completely different search filter

I'm no LDAP expert and I don't even know if it's possible to use regular expressions inside the search filters.

Does anyone know if it's possible and how?

P.S. I cannot pre-process the username to strip the domain. This cannot be changed, as it's all part of a large system.
