Limit use of deprecated krb5 mech OIDs
Filter out mechs with the GSS_C_MA_DEPRECATED attribute from the set
of mechanisms obtained by SPNEGO, and from the set used when
gss_acquire_cred() is called with no desired_mechs attribute.
SPNEGO acceptors will still accept the old and wrong krb5 OIDs, but
SPNEGO initiators will not offer them. According to [MS-SPNG], only
Windows 2000 does not recognize the standard krb5 OID, and it is
In gss-client.c, use the standard krb5 OID for the -krb5 option, as
acceptors who call gss_acquire_cred() with no desired_mechs to create
an acceptor cred will no longer accept the old or wrong krb5 OIDs.
