Question: When I use `man fcntl' got the message:

```
No manual entry for fcntl

```

which the pkg is needed to install?

ps. I use debian.

Answer: 
Ah. I think I see the problem.

My login is in builtin\Administrators which is a member of the server fixed role sysadmin.

Therefore I'm a member of sysadmin, which means I'm dbo and won't see any role or group information.
Check your `ERRORLOG` and see if there is any error indicating that the SQL Server service cannot connect to the 'domain' Active Directory.
