| # 4.1.2.4 - SASL GSSAPI Authentication |
| |
| This authentication mechanism is specified in the following RFCs : |
| |
| * [RFC 4752](http://tools.ietf.org/html/rfc4752) |
| |
| It's more specifically used for Kerberos V5 authentication. As **Apache Directory Server** is also a _Kerberos Server_, it comes as a natural extension of the server. |
| |
| It requires some configuration though. |
| |
| ## Configuration |
| |
| The idea is for the **LDAP** server to delegate the authentication to the **Kerberos** Server. |
| |
| |
