User could not be found on the system:: No error information

Get the error ’User could not be found on the system: No error information" in /home/{username}/ezsh.log.  Users are not found even though id  <username> returns the UID and GID. This happen when you have configured ezeelogin with pam_ldap. This happens because service nscd is not running and restarting it would fix the issue. Also it is recommended to reduce the positive-time-to-live  to a minute or two
