Use the @@authmech global variable to determine the authentication mechanism Adaptive Server uses.
For example, if Adaptive Server is enabled for LDAP user authentication with failover (enable ldap user auth = 2) and user “Joe” is an external user with authentication set to ANY, when Joe logs in, Adaptive Server attempts to authenticate Joe, using LDAP user authentication. If Joe fails authentication as a user in LDAP, Adaptive Server authenticates Joe using Adaptive Server authentication, and if that succeeds, he logs in successfully.
@@authmech global has this value:
select @@authmech ---------------------------------- ase
If Adaptive Server is configured for strict LDAP user authentication (enable ldap user auth = 2) and Joe is added as a valid user in LDAP, when Joe logs in, the value for @@authmech is:
select @@authmech ---------------------------------- ldap
