Why does my server running nscd and nss-ldap stop responding and users are prevented from logging in through ssh?

Solution Unverified - Updated -


  • Users cannot ssh onto the server and it appears to not be responding.
  • The message logs shows below error message.
sshd[23638]: fatal: Privilege separation user sshd does not exist
nscd: nss_ldap: reconnected to LDAP server ldaps://ldaps.test.com/ after 1 attempt
  • Without restarting / reloading nscd service, server does not respond and does not allow to login via ssh.
  • Or samba throws an error 'permission denied' while accessing 10 level depth directories


  • Red Hat Enterprise Linux 5
