Use mod_auth_gssapi instead of mod_auth_kerb
Change configuration on new installs only. Enable GssapiLocalName so we have access to the local name in REMOTE_USER and the full principle in GSS_NAME. Enable GssapiSSLonly even though SSLRequireSSL is also set. The belt and suspenders principla. Signed-off-by: Rob Crittenden <> Reviewed-by: Simo Sorce <>
