When working with 2 LDAP in Multi Mode, LDAP connexion not reinitialized on second LDAP if user not found in first LDAP
in multi mode with 2 LDAP backends
if user not found in first LDAP, there is a bug when switching on second LDAP because LDAP connexion is cached and not reinitialized
suggested patch joined to disable cache on LDAP connection, but there may be a cleaner way to fix the bug
