NOTE: PAM has no concept of realms, partly because the *nix UID/GID namespaces are flat, so you can only use PAM_KRB5 to get initial creds for users in one realm. > - pam_krb5 does Kerberos authentication > > Has anybody tried/done this? Not I, but nowadays PAM app developers have become used to the possibility that PAM may change PAM_USER during pam_authenticate(), so I'd expect this to work, modulo Radius.
