Did you by any chance just add username to abbagroup? This kind of change takes effect when you log in, and applies to the login process and its descendants.

When you run groups username, it tells you which groups username would belong to if (s)he logged in. Run groups with no argument instead, so that it tells you which groups the current process belongs to. If that doesn't show abbagroup, you need to log out and back in.

I'm attempting to run the command
```
username> ls -al var/
```
But I get the exception
```
ls: cannot open directory var/: Permission denied
```
When I check the permission of the directory I see
```
drwxr-x--x  6 sysuser abbagroup   4096 2010-07-28 11:55 var
```
I've confirmed that my user account is part of the group
```
> groups username
username: abbagroup
```
So why can't I run the command?

  Does it show properly when you ssh or telnet to the box, as opposed to just opening a console from your desktop?

  Running sudo ls -al var/ returns drwxr-x--x 6 sysuser abbagroup 4096 2010-07-28 11:55 . drwxr-xr-x 10 sysuser abbagroup 4096 2010-09-08 12:45 .. drwx--x--x 3 sysuser abbagroup 4096 2010-07-28 11:55 lib drwx--x--x 3 sysuser abbagroup 4096 2010-07-28 11:55 log drwx--x--x 4 sysuser abbagroup 4096 2010-07-28 11:55 run drwx--x--x 5 sysuser abbagroup 4096 2010-07-28 11:55 spool

  Does id also show abbagroup for that user?
