Allow for manual configuration of LDAP base

In a situation where the looked up LDAP base is cn=example,cn=com, It appears, that it is not possible for the user to change the base to something like ou=fd,cn=example,cn=com.

Having FusionDirectory data in it's own OU with an associated FD user in LDAP would be good security practice (The requester thinks).
