[Ubuntu] failling joining ubuntu to domain

[RabbieBurns]

Ive setup the samba and all other things according to this guide , but its failing when trying to join the domain:

root@FREERADIUS:~# net ads join -U rabbieburns
Enter rabbieburns's password:
Failed to join domain: failed to set machine spn: Operations error

and i cant find any answers anwyerre on google.

kinit rabbieburns@MY.DOMAIN.COM

is successful and

klist

shows a valid kerberos ticket...

Any ideas would be much appreciated!

That's a very old guide from 2005. I wrote one recently for Ubuntu 10.04: Run Level 3 » Blog Archive » Ubuntu 10.04 Active Directory Authentication

Anything obvious in the log file?

interestingly, even though that it said

Failed to join domain: failed to set machine spn: Operations error

IT created the machine account in AD, and seems to do ntlm_auth etc, and also lets me login to ssh using AD accounts

Im still not sure quite whats going on just now, but will read your blig and have a look,

Thanks
