The objectid.dat file maps global object identifiers (OIDs) to local names. It is located in the $SYBASE/config directory in UNIX, or the %SYBASE%/ini directory in Windows.You need to edit this file only if you have changed the local name of a security service in the libtcl.cfg file.
A sample entry in the objectid.dat file for DCE is:
[secmech] 1.3.6.1.4.1.897.4.6.1 = dce, dcesecmech
A sample entry in the objectid.dat file for Kerberos is:
[secmech] 1.3.6.1.4.1.897.4.6.6 = csfkrb5, kerberos
