Enable server
The Enable checkbox is marked by default to make the server available for user
authentication.
Name
Enter a meaningful name for the external LDAP/active directory authentication server.
Precedence
Optional. If you are setting up multiple external LDAP/active directory authentication
servers and need to establish the order in which the BSC checks the servers for user
authentication, select the server's priority from the Precedence drop-down list.
Note that 1 means the server is checked first. The precedence you configure does not
apply to Transparent NTLM Windows logins, Transparent 802.1x logins, or local users in
the BSC database, because these authentication schemes are always checked first.
If you set a Precedence for a server that is the same as that set for a previously configured
server, the previous server's Precedence, and that of all servers having a lower
configured precedence, is incremented by 1. For example, if server A already has a
Precedence of 1 and server B's is 2 and you then set server C's to 1, server A's
Precedence becomes 2 and server B's becomes 3.
