Weird permission problem

[Stanton, Curt (NCI/IMS)]

I have two users UserA and UserB
They both belong to GroupA

DirA is where all the files are
UserA is the owner of DirA and
GroupA is the group of DirA

The problem is that UserB can only commit files that he owns, but UserA can
commit any file.
What might the problem be?

We have other projects that work fine and don't have this problem.

Thanks for any help
