-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 According to Corinna Vinschen on 1/22/2007 2:34 AM: >> When "id" is called without a username, it calls the getgroups(...) function >> which appears to work as expected. However, when a specific username is >> passed, even the username of the current user, getugroups(...) is called, >> and does _not_ appear to work as expected. > > That's by design. getgroups() has access to the user token of the > current process and returns every group which is in this token. > getgrent() is a function which enumerates /etc/groups. So my translation of this would be that the bug is not in id, but in the fact that your /etc/groups is out-of-date. Use mkgroups to remedy the situation. - -- Don't work too hard, make some time for fun as well!
