Re: Re: Retrieve unix group membership for a uid in a perl CGI

And then you move to a system running NIS or LDAP and miss anything not defined in the local /etc/group file. This is why you go through getgrent which uses the system's group reading libraries and honours nsswitch.conf (or whatever).

I was going to use getgrent, for the guy's answer, and I couldn't get it to work.... Until now: I just realized that instead of looping through /etc/group, you can loop through getgrent. The thing I didn't immediately realize is that getgrent returns different values on subsequent calls. (Since I've never done this particular thing before, I was testing the code before posting...)
