Description Chia-Ling Lee 2006-12-01 00:37:48 EST
Description of problem:

I have a number of Ubuntu Linux clients talking to an FC5 server. 
The FC5 server runs Kerberos for authentication and LDAP for session
information. The LDAP is NOT used for authentication. 

In Ubuntu 6.06, libnss-ldap works as expected. Users need not be in 
/etc/passwd, /etc/group and they can still authenticate locally. 

In Ubuntu 6.10, libnss-ldap would not work. Searching for bug reports
extensively, I found a posting that it is a upstream debian bug. I
have to live with it for the moment. 

So now, I installed FC6. It works fine, but again, nss_ldap would not
work, and I have to set up users locally in /etc/passwd and /etc/group. 

I am just wondering, if FC6 and Ubuntu 6.10 has a similar problem, then
perhaps the bug is further upstream than debian? Perhaps someone in 
Fedora Core or Red Hat might want to look at it. 

Version-Release number of selected component (if applicable):

Ubuntu 6.06: libnss-ldap 238-1.1ubuntu1
Ubuntu 6.10: libnss-ldap 251-5.2
FC6:         nss_ldap that comes on the install disk does not work
             nss_ldap that is install after yum update would also not work

How reproducible:
Very; ldapsearch -x -ZZ works on both 6.10 and FC6, so I know my 
ldap.conf file and cacerts are fine. Just won't work if /etc/nsswitch.conf 
is amended to include ldap for passwd and group.

Steps to Reproduce:
1. Install FC6, configure it to do Kerberos Auth and LDAP for user info. 
2. User login fine. ldapsearch -x -ZZ works fine.
3. Change /etc/nsswitch.conf to append ldap. id <userID> hangs. gdm is slow. 
4. getent passwd or getent group hangs
Actual results:
Hang on login or user query. 

Expected results:
It should have worked and the commands should respond immediately.
