LDAP request changes
Created by: balcirakpeter
- Added new functionality resolve_domain_controlers to ADConnector.pm, which resolve all available domain controlers from a hostname. Added also method ldap_connect_multiple_options which try to connect to the first available controler from the list of controlers.
- Updated services for this functionality used in MUNI AD. ad_ceitec is set up manually and vsup services cannot be updated yet because, the NET::DNS::Resolver perl module need to be installed on the server first.
