RE: Heimdal and r* client programs

Actually, Simon's patches do reference the Heimdal and MIT krb5 APIs in addition to GSS-API, specifically for credentials handling (i.e., writing out ccaches) and account authorization (i.e., krb5_kuserok()). But aside from that Simon's patches use GSS-API and, in any case, work with Heimdal and MIT.
