To be conistent with symfony@db46f3b, also add the LDAP error number to the exception in this case.

This is especially useful to perform a reconnect for long running php processes without doing something like this: ```if(str_contains($ex->getMessage(), 'LDAP error was [-1]')) {```
Or to check for a ```[32] No such object``` error.
