[Mageia-dev] Help needed with ldap server.and gdm.

Sat Mar 23 21:41:43 CET 2013

+I've been working on getting an ldap server working in Mageia 2,
+and have a strange error, that I'm not sure how to debug.
+
+I have two users. The user dave existed before adding the ldap
+server, and is defined in both /etc/passwd (group and shadow too),
+as well as in the ldap database. The user qatest is only defined
+in the ldap database.
+
+I've been using the instructions from
+http://linsec.ca/Using_OpenLDAP_for_User_Authentication#Configuring_PAM_to_use_LDAP
+
+In the auth section of /etc/pam.d/system-auth, if I use
+auth        sufficient    /lib/security/pam_pwdb.so likeauth nullok
+both users are listed by gdm, but only the qatest user can login,
+and the "su -" command fails with "unknown pam error". The user
+dave can login ok in run level 3, and startx, but also cannot use
+the "su -" command, or login via gdm
+
+If I use the line
+auth        sufficient    /lib/security/pam_unix.so likeauth nullok
+both users can login with run level 3, startx, and use "su -", but
+the qatest user is not listed by gdm, so can't login with a normal
+run level 5 startup, while the user dave can.
+
+So it looks like I should be using pam_unix, but need something to
+get gdm to list the ldap only user.
+
+Any suggestions?
+
+Thanks, Dave Hodgins
