rdesktop, credSSP and kerberos

Question

I have installed the program rdesktop with the command

sudo apt-get install rdesktop

I use rdesktop with the command

rdesktop -a 32 192.168.0.38

with the error message

Disconnected due to network error, retrying to reconnect for 70 minutes. ERROR: CredSSP: Initialize failed, do you have correct kerberos tgt initialized ?

How do I fix the error?

Thanks by advance,

Note: Sorry for my english, i'm french

I solved this by using xfreerdp instead. I actually tried configuring the Kerberos authentification, but gave up after an hour.

So an example of an xfreerdp command would be:

xfreerdp /u:'DOMAIN\john' /p:'doe' host:port

Hope that helps even though it's a bit late :-)

Had the sameproblem: KDE's `krdc` also does not have that issue. But using it of course means a lot of KDE libraries to be installed first.... – FelixJN Jun 14 '17 at 11:43

Shouldn't it be /v:host:port ? – Lauri Elias Jul 10 '18 at 11:12

another way is to acquire a ticket from the kerberos server in case you are in a domain. NLA is an extra security layer which requires the client to authenticate against the Domain before logging on. After krb5.conf is adequately configured for the domain (google it), you can do the following:

kinit <user>
rdesktop -u <user> -d <domain>

You only need to execute kinit once until the ticket has expired

Not sure if following, most of the answers suggest this, but how is possible for xfreerdp to do the connection without touching krgb5.conf? – carpinchosaurio Nov 09 '21 at 17:03
