LDAP Client not connecting to LDAP server
I have very limited knowledge on LDAP configuration and have been trying fix one issue, but unsuccessful.
The server, I am working on, is Solaris-10 zone. sudoers is configured on LDAP (its not on local server). I have access to login directly on server with root, but somehow sudo is not working for any user. I did restart service with "svcadm restart svc:/network/ldap/client:default" but no luck.
Code:
[ greog@sms-prod-sim2:/ ]
$ /usr/local/bin/sudo su -
sudo: ldap_sasl_bind_s(): Can't contact LDAP server
sudo: no valid sudoers sources found, quitting
sudo: unable to initialize policy plugin
[ greog@sms-prod-sim2:/ ]

From /var/adm/messages --
Code:

"sudo" cannot contact the LDAP server it is supposed to. That's quite clear. I'm not sure restarting the ldap client service will affect this sudo implementation. You need to find the non standard sudo configuration file, "sudo.ldap" or similar, maybe under /etc/local and see what is declared here.

There is /usr/local/etc/sudoers but there is NO entry in there. Its sudoers configuration is being picked from LDAP server. So I am assuming, if this client is able to reach to LDAP server, issue should be fixed.

Sure, there is no sudoers file. That's the whole point of centralizing it on a directory server.

You need to find the file where sudo configuration is stored. This is not the sudoers file which contains sudo policy configuration but the sudo front-end one, likely sudo.conf.

Anyway, is there a directory server running on ngsic-pre-ppt.com?

"find / -name *sudo*" didn't gave any relevent location.
Yes, ngsic-pre-ppt.com is directory server

Should be:
Code:
find / -name "*sudo*"

or directly
Code:
strings /usr/local/bin/sudo | grep "^/"

So the issue might be wrong credentials. You should have a look to the directory server logs and see if there is a bind failure from your sudo host.
