[Fedora-directory-users] pam_ldap: error trying to bind as user (Constraint violation)

[Aaron Cline]

Hello:

I'm using FedoraDS 1.0.3 to perform authentication functions to servers in a
DMZ.  This morning a user was able to log in but then 1 minute later they
tried to use sudo as themselves and they were denied.  They continued to be
denied for the next 10 minutes before they gave up.  I pulled the following
errors from the system log of the system they were logged into:

Mar  5 14:24:37 low-tcw-103 sudo(pam_unix)[10957]: check pass; user unknown
Mar  5 14:24:37 low-tcw-103 sudo(pam_unix)[10957]: authentication failure;
logname=marnelc uid=0 euid=0 tty=pts/1 ruser= rhost=
Mar  5 14:24:37 low-tcw-103 sudo[10957]: pam_ldap: error trying to bind as
user "uid=marnelc,ou=ISG,ou=Lowell,ou=People,dc=pii-dmz,dc=ext" (Invalid
credentials)
Mar  5 14:24:43 low-tcw-103 sudo(pam_unix)[10957]: check pass; user unknown
Mar  5 14:24:43 low-tcw-103 sudo[10957]: pam_ldap: error trying to bind as
user "uid=marnelc,ou=ISG,ou=Lowell,ou=People,dc=pii-dmz,dc=ext" (Constraint
violation)

It looks to me that the first time the user must have typed the wrong
password, but after that I don't know what happened.

I don't see any obvious errors in either the access or error log files on
the LDAP server.  Has anyone seen this before?

Thanks for any info or advice.

Aaron/All,
       I'm seeing the same thing with logins via ssh, on rhel 4 the error
logs as:
 "pam_ldap: error trying to bind as user
"uid=name,ou=People,dc=domain,dc=com" (Invalid credentials)"
rhel 3:
 "pam_ldap: error trying to bind as user
"uid=name,ou=People,dc=domain,dc=com" (Constraint violation)"

The user works on another rhel4 box with the same config as the one throwing
the error, so I'm at a loss.
