Best approach to shorten long DNs (snc/identity/as)

Hi guys,

does anyone know the best approach since SSO 3.0 and CommonCryptoLib how to shorten long certificate DNs? I remember vague to a gss_alias function but don't know for sure. The ccl/snc/namealias/ only works for client certificates. I am looking for ways to shorten a long SNC identity (server certificate).

Thank you.

Cheers, Carsten
