I'm trying out sssd-kcm on Fedora 30 and it appears to break rdesktop. I'm now getting:
Failed to initialize NLA, do you have correct Kerberos TGT initialized ? Core(debug): GSS error [0:13:0]: cssp_connect(), negotiation failed. Core(debug): - Unspecified GSS failure. Minor code may provide more information Failed to connect using NLA, trying with SSL Failed to connect, CredSSP required by server (check if server has disabled old TLS versions, if yes use -V option).
I bumped up the debug level on sssd_kcm and it seems to be fine - I see a request for a credential and it sends a reply.
Any suggestions on what to check next?
