I don't think this is critical because it is more of a user error we
happened to run wbinfo --group-info for a user versus a group on accident.
Let me know if you want more info than crash in the below log output.
samba 4 alpha 14 -- started with no extra arguments
RHEL 6.1 64-bit
Commands run:
----------------------
[root at myhost bin]# wbinfo --group-info <<USERNAME>>
failed to call wbcGetgrnam: WBC_ERR_DOMAIN_NOT_FOUND
Could not get info for group <<USERNAME>>
[root at myhost bin]# wbinfo --group-info <<REAL_GROUP_NAME>>
failed to call wbcGetgrnam: WBC_ERR_WINBIND_NOT_AVAILABLE
Could not get info for group <<REAL_GROUP_NAME>>
[root at myhost bin]# wbinfo --group-info <<REAL_GROUP_NAME>>
failed to call wbcGetgrnam: WBC_ERR_WINBIND_NOT_AVAILABLE
Could not get info for group <<REAL_GROUP_NAME>>
After running the above commands:
