It comes back with:
# L_GETIDENTITY_TEST=true l_getidentity -d 48
uid=48 gid=48
permissions:
nid perm
The only thing in /etc/hosts is the localhost. Everything else is via DNS that is all there (forward/reverse/aliases, etc)

Is the web server UID/GID in the /etc/hosts file on the MDS so that the l_getidentity upcall can find them? Try running on the MDS as root:
L_GETIDENTITY_TEST=true l_getidentity -d {uid}
and verify that the user can be found.
