No clue about the subject - I'm using Gmane to reply, since I'm usually without reliable SMTP access. If group membership IS currently required to be listed in /etc/group for these functions (groups, id, getugroups(), getgrent(), etc...), shouldn't mkgroup -ul, with the "-u", be run by default at Cygwin first-run? Also, including this better in the documentation would be a plus. Also, "mkgroup -u" has a bug, as far as I'm concerned. It always includes the Windows' username, even if renamed in /etc/passwd for Cygwin-purposes. For example, take a Windows username of "John Smith". I renamed the first field in /etc/passwd to "jsmith" to avoid the space. "jsmith" should (and needs) to be included in the gr_mem field, not "John Smith", otherwise all of the above functions fail to see that this user is a member of any groups... I do see one issue with implementing the OS-group-calls into Cygwin - Win95/98 don't have any concept of user groups. This would have to be accounted for... Maybe I'll convert the http://http://cygwin-getugroups.pbwiki.com/ site to address the possibility of adding this functionality...
