LDAP Authorization
8 Select Allow Unsecure Traffic to allow unsecure LDAP connections.
When this check box is clear, all LDAP connections are secure.
9 In Administrator Bind DN , type the Administrator Bind DN for queries to your LDAP directory.
The following are examples of syntax for Bind DN:
“domain/user name”
“ou=administrator,dc=ace,dc=com”
“user@domain.name” (for Active Directory)
“cn=Administrator,cn=Users,dc=ace,dc=com”
For Active Directory, the group name specified as cn=
groupname is required. The group name that
is defined in the Firebox SSL VPN Gateway must be identical to the group name that is defined on
the LDAP server.
For other LDAP directories, the group name either is not required or, if required, is specified as
ou=
groupname.
The Firebox SSL VPN Gateway binds to the LDAP server using the administrator credentials and then
searches for the user. After locating the user, the Firebox SSL VPN Gateway unbinds the
administrator credentials and rebinds with the user credentials.
10 In Administrator Password , type the password.
11 In Base DN (where users are located), type the Base DN under which users are located.
Base DN is usually derived from the Bind DN by removing the user name and specifying the group
where users are located. Examples of syntax for Base DN:
“ou=users,dc=ace,dc=com”
“cn=Users,dc=ace,dc=com”
12 In Server login name attribute , type the attribute under which the Firebox SSL VPN Gateway
should look for user logon names for the LDAP server that you are configuring. The default is
sAMAccountName. If you are using other directories, use cn.
13 Click Submit .
If a user is not located in an LDAP directory or fails authentication on a server, the Firebox SSL VPN Gate-
way checks the user against the user information stored locally on the Firebox SSL VPN Gateway.
LDAP authorization requires identical group names in Active Directory, on the Firebox SSL VPN Gateway,
and on the LDAP server. The characters and case must also be the same.
Note
For further information to determine the LDAP server settings, see “Determining Attributes in your
LDAP Directory” on page 78

LDAP Authorization
The following is a discussion of LDAP group memberships attributes that will and will not work with
Firebox SSL VPN Gateway authorization.
You can use the following authorization types with LDAP authentication:
• Local authorization
• LDAP authorization
•
No authorization
If you are using double-source authentication, authorization is based on the primary authentication
method, not the secondary authentication method.
