If there were any issues with connection to LDAP server (either networking issues, or restart of LDAP server), after the connection is restored user is unable to log in to DB.
STR:
1) start PSMDB
2) restart LDAP server or temporary break connection to LDAP
3) connection to LDAP server is restored
Actual behavior:
User can't log in due to error 'Can't contact LDAP server', restart of PSMDB helps to resolve the issue
Expected behavior:
User is able to log in without restart
