The security mechanism option enables Kerberos authentication for connections to the remote server.
As of Adaptive Server release 15.7, Kerberos is the
security mechanism supported by Adaptive Server. The rpc
security model A and rpc security model B are
no longer required for enabling security mechanism for remote mechanisms
and sp_helpserver will not display the
rpc security model. For backward compatibility, databases that use
DCE mechanism upgraded to this release will continue to work as
earlier.
