LDAP NULL Base Connection

Medium Nessus Network Monitor Plugin ID 1954


The remote host may give an attacker information useful for future attacks.


Improperly configured LDAP servers will allow the directory BASE to be set to NULL. This allows information to be gathered without any prior knowledge of the directory structure. Coupled with a NULL BIND, an anonymous user can query your LDAP server using a tool such as LdapMiner.


Disable NULL base connections.
