[Samba] wbinfo -i : Could not get info for user

[Victor Sudakov]

Colleagues,

What could be the reason of "wbinfo -i" not working? 

root at fs02-sibptus:~# wbinfo --domain . -u | grep sudakov
SIBPTUS\sudakovva
root at fs02-sibptus:~# wbinfo -n sudakovva
S-1-5-21-839522115-2139871995-725345543-1110 User (1)
root at fs02-sibptus:~# wbinfo -i SIBPTUS\\sudakovva
Could not get info for user SIBPTUS\sudakovva
root at fs02-sibptus:~# wbinfo -i sudakovva
Could not get info for user sudakovva
root at fs02-sibptus:~# wbinfo -S S-1-5-21-839522115-2139871995-725345543-1110
Could not convert sid S-1-5-21-839522115-2139871995-725345543-1110 to uid
root at fs02-sibptus:~# net rpc testjoin
Join to 'SIBPTUS' is OK
root at fs02-sibptus:~#

Is it some misconfiguration? Thank you in advance for any input.
