Hi

I have a redhat system that uses LDAP. I have very little experience with LDAP and was trying to figure out how the groups work. I managed to retrieve list of of users with perl-ldap cm\ommands and then saw that the groups I,ve been looking for are actually also listed there.
Users have a ou=users and the groups have ou=groups.

Is there a way now to retrieve a list of users that belong to a specific group like "Students" with perl-ldap and print it to a file?

You should just need to do another query like you presumably are to get the user list, you can run this within the scope of your users OU to increase efficiency, or a top level sub tree search.

The query should look something like:
(&(objectClass=user)(memberOf=CN=TestG123,OU=Groups,DC=TESTDOM,DC=local))

Where CN=TestG123,OU=Groups,DC=TESTDOM,DC=local is the Distinguished name (DN) of the group you want to get the members for.

$mesg = $ldap->search(
    base  => "OU=Users,DC=TESTDOM,DC=local",
    filter => "(&(objectClass=user)(memberOf=CN=TestG123,OU=Groups,DC=TESTDOM,DC=local))",
    scope => 'sub'
);
