If user certificate has oid number i.e.0.9.2342.19200300.100.1.1 in the subject instead of uid (userid). Can this oid number be mapped in SiteMinder 12.51 for certificate mapping for doing certificate based authentication?
I honestly do not have a direct answer for this. However have you tested this on a pre-Prodn Environment or playpen environment. A quick test would suggest, if it works OR not. My gut feeling is that it may work unless I am missing something.
You'd also need to review your User Directory configuration to make sure it aligns correctly to disambiguate with what is being passed in Subject of the Certificate.
If it does not work, could you gather the Policy Server Trace logs for debugging purposes. The Policy Server trace log would suggest what precisely is happening underneath.
