The branch, v3-6-test has been updated
via dde9059 Make getpwnam_alloc() static to lib/username.c, and ensure all username lookups go through Get_Pwnam_alloc(), which is the correct wrapper function. We were using it *some* of the time anyway, so this just makes us properly consistent.
from f74e696 s3: Cope with EINTR in smbd_[un]lock_socket (cherry picked from commit da00021a7c236f9ac87442b96881bf0b2701ad0b)

commit dde9059287f24e920d5100933dbff1f03c09f326
Author: Jeremy Allison <jra at samba.org>
Date: Wed Oct 20 11:06:06 2010 -0700
Make getpwnam_alloc() static to lib/username.c, and ensure all username lookups go
through Get_Pwnam_alloc(), which is the correct wrapper function. We were using
it *some* of the time anyway, so this just makes us properly consistent.
Jeremy.
