The MIT Kerberos security mechanism is now available on DB-Library, providing network and mutual authentication services. This feature allows older Sybase applications to use Kerberos authentication services, with less need for modification and recompilation.
The following DB-Library macros were added to enable Kerberos support:
DBSETLNETWORKAUTH – used to enable or disable network base authentication.
DBSETLMUTUALAUTH – used to enable or disable mutual authentication of the connection’s security mechanism.
DBSETLSERVERPRINCIPAL – used to set the server’s principal name, if required.
DB-Library only supports network authentication and
mutual authentication services in the Kerberos security mechanism.
