Hello I've been running samba3 via mac ports on osx for quite sometime. I don't use it very often but recently I noticed I could no longer login. I know I've done system updates to osx, but now I get some weird error when trying to start it.

osx:~ rick$ sudo /opt/local/sbin/smbd -i
smbd version 3.6.6 started.

I've run into the same issue recently. It seems to be a problem that's already known for a long time, but haven't been fixed in mac ports yet.

The problem is that the root user is in more than 64 groups (which seems to be some kind of a hard limit), which is causing problems.

I'm using Samba 3.6.5 from Homebrew on Montain Lion and it's working fine for me.

There has been a lot of discussion about this issue here:
