[Samba] domain join becomes invalid every 24h

[Alexis Pellicier]

I've activated the logs as Andrew suggested and It has shown the
fileserver was trying to join the domain with 2 different names.
I guess I messed something up when I did some testing on joining the domain.

I have found those 2 names in the AD and in krb5.keytab.
So I've deleted the faulty name from AD,
samba-tool computer delete testfileserver
leave the domain,
net ads leave -Uadmin
 move away krb5.keytab and join the domain again.
mv /etc/ krb5.keytab
net ads join -Uadmin

After 24h every the join is still ok. Proble solved

Thanks you a lot for your help !
