LDAP user cannot login to one server but can on others.

Trusted Contributor

LDAP user cannot login to one server but can on others.

I have an LDAP user that cannot login to one particular box but can on others. Other LDAP users can login fine.

His password has been reset on LDAP server.  I have restarted ssh and ldapclient.

 sshd_config has   UsePAM yes


When I switch to user and then try to su - ldapuser  I get:

The password is not expired. But server thinks it is.


#su - ldapuser

$ su - ldapuser
Last   successful login for ldapuser: Fri Feb 10 13:26:19 CST6CDT 2012
Last unsuccessful login for ldapuser: Fri Feb 10 13:15:53 CST6CDT 2012
Your password has expired.
su: Sorry


In the syslog.log I get for this su - ldapuser session:


su: pam_acct_mgmt: error Permission denied
su: pam_acct_mgmt: error Get new authentication token

su: pam_acct_mgmt returned 7


For remote ssh to this server as ldapuser I get:


sshd[11226]: error: PAM: Permission denied for ldapuser from host1









Why does PAM or ldap deamon or ssh  think the password is expired and how do you reset that account on that one server if its LDAP bound and trusted?  modprpw -k is for local accounts resets is it not??

Re: LDAP user cannot login to one server but can on others.

What does getprpw return for the local account?  assuming there's a local unix account as per your reference to /tcb/files/auth/l/ldapuser


/usr/lbin/getprpw -l ldapuser

/usr/lbin/getprdef -m exptm,lftm


Is there a password assigned to the local ux account, if so has it expired...  anyhow, I'm betting there is a local ux passwd on the problem box which has expired.  If you compare that to the working box, I bet it isn't expired (yet).


Regardless, if you don't want the user to authenticate using a local ux passwd and only ldap then you should have a closer look at your pam.conf to see where in the stack it fails on a 'required' module. 


good luck
