Hi,
I'm new to LDAP. I just created a new user in LDAP and it cannot login through ssh. It keeps prompting for the password. Any help will be greatly appreciated.

Hi Rodney,
There are a million ways ssh auth can fail - bad sshd_config, bad PAM config, bad LDAP client config, LDAP server side problem.
Best to try to test the LDAP authentication first.
can you try something like (on one line)
ldapwhoami -H ldap://your.ldap.server -x -W -D uid=dude12,ou=people,dc=wh,dc=local
Enter the password when prompted and if it replies with
dn:uid=dude12,ou=people,dc=wh,dc=local
Then that bit works...
Then see if
getent passwd
on the client returns a list of uses with dude12 in.
Then post your pam configs and pam_ldap.conf and libnss_ldap.conf (or equivalent according to distro).
Hi Tim/Rodney,
I have a question related to Rodney's question. Hope that you or someone can help, it is greatly appreciated. I tried to configure PAM for rlogin from Client machine which I expect to authenticate user credential on the LDAP Server. It always fails. I haven't configured security for SASL/TLS between Client/Server LDAP. Do I need to configure SASL/TLS in order for PAM to work?

Hi,
In short, no - unless you have configured the server to *require* TLS. PAM makes no special requirements except what you configure in /etc/pam.d/ and pam_ldap.conf (or equiv).
The rest of your message will take some thinking - I'll try to have a look later - but I'm not familiar with rlogin.
