When you first create the method for the domain, you must enter the 
authentication ID. After you have created the method and defined a name for it,

groupauth <auth IDs>

Specifies one or more preconfigured LDAP or Local 
database authentication schemes (not including the 
current one) that will be used to retrieve the user’s 
group information after the user has been 
authenticated.

To specify more than one authentication method to use 
for authorization, enter the auth IDs separated by a 
comma (,).

secondauth <auth ID>

Specifies a second authentication service to be used 
after the first one succeeds. The feature supports 
single sign-on to backend servers in cases where the 
first authentication method is token based or uses 
client certificate authentication.
