Field Description Usage tips
Bind
username
Username of the account that the VCS will use to log
in to the LDAP server (case sensitive).
Only required if SASL is enabled.
Configure this to be the
sAMAccountName; Security Access
Manager Account Name (in AD this is the
account’s user logon name).
Directory configuration: this section specifies the base distinguished names to use when searching for account
and group names.
Base DN for
accounts
The ou= and dc= definition of the Distinguished
Name where a search for user accounts should start
in the database structure (case insensitive).
It is important to specify the DN in the order ou=,
then dc=
This is for authentication of both
administrator login and user login
requests.
The Base DN for accounts and groups
must be at or below the dc level (include
all dc= values and ou= values if
necessary). LDAP authentication does
not look into sub dc accounts, only lower
ou= and cn= levels.
Base DN for
groups
The ou= and dc= definition of the Distinguished
Name where a search for groups should start in the
database structure (case insensitive).
It is important to specify the DN in the order ou=,
then dc=
This is for authorization of an
authenticated user to log in as an
administrator or to log in to a user
account.
If no Base DN for groups is specified,
then the Base DN for accounts will be
used for both groups and accounts.
