Thanks for responding.

I changed log level to 3 and was able to see an NT_STATUS_ACCESS_DENIED
error when trying to change the name of a file I just created.

If I change the directory (/home/chemgroup/username) permissions from this:

   drwxr-x---

to this:

   drwxrwx---

the user username can write, rename, and delete just fine. I don't see
how the Linux permissions should affect this, because username already
is the owner of the username directory with rwx permissions.

I should not that our passdb is ldap, but I can authenticate just fine.
It is not use NTLM for auth.  It is using userPassword on the LDAP
server for auth.
