CentOS - Aug 2014 - Zombie users in Centos6

Geetings,


I have a machine with PAM using LDAP.
Some old users do not disappear from:

  * getent passwd

But, they are not in:

  * /etc/passwd or
  * LDAP

Where are they?
Any idea?

Please, I am affraid of ghost. :-(


TIA

Usually when you use LDAP for NSS you have a caching daemon to cut down on the
number of round trips and latency (every time you need to map a userID to a name
requires a call to LDAP) so maybe your cache is not expiring the old entries
yet.  NSCD which comes with GLIBC is a common cache, otherwise SSSD or WINBIND
are also commonly used.  Restarting your cache should help.
