Subject: creating posgres service principal 


I have found some information in the Samba and beyond 
And this what I did 
# samba-tool user create postgres-servername 
# samba-tool spn add postgres/servername.domain_name at REALM postgres-servername 

The following command: 
# samba-tool domain exportkeytab /root/krb5.keytab --principal=postgres/servername.domain_name at REALM 

generates the following exception 

ERROR(runtime): uncaught exception - Key table entry not found 
File "/usr/local/samba/lib/python2.7/site-packages/samba/netcmd/__init__.py", line 175, in _run 
return self.run(*args, **kwargs) 
File "/usr/local/samba/lib/python2.7/site-packages/samba/netcmd/domain.py", line 103, in run 
net.export_keytab(keytab=keytab, principal=principal) 

What did I do? 

by the way 
When I check list of the service principal(s) for the user postgres-servname, the principal mentioned above does belone the user psotgres-servername 
I ran the following command # sam-tool spn list postgres-servername 
Also I can export the key tab for the the default principal krbtgt 
using the following command 
# samba-tool domain exportkeytab /root/outfile.keytab 

Is the switch --principal working?
