Question

RHEL5 LDAP Authentication to Active Directories

Asked by: bebo_c

I am trying to setup a RHEL5 client to authenticate with Win2003 AD. I have the ldap.conf and krb5.conf setup and it seems to be authenticating when I use:

 [root@client1 etc]# /usr/kerberos/bin/kinit joeblo@LAB01.TEST.LCL
Password for joeblo@LAB01.TEST.LCL:
[root@client1 etc]#

The krb commands (klist,kbinit, etc.) seem to work but I cannot seem to login from a remote terminal. It just hangs when I enter my password. I think I am missing something. I think that PAM might not yet be setup???? I have limited docs...

I have attached the krb5 and ldap.conf files

Any ideas?

I would recommend you to take a network trace on the Windows KDC in order to examine the Kerberos/LDAP traffic that is being generated.
Im pretty sure you will be able to find some clues there. or at least some generic error codes
Use Wireshark is easier.
