DCE authentication patch (version 0.5) for qpopper 2.3
------------------------------------------------------


This patch adds DCE authentication to qpopper version 2.3, Qualcomm's
free POP server. It allows you to use the DCE registry to authenticate
POP users, and to serve mail from DFS.


To apply the patch, acquire and untar the qpopper distribution, change into
the qpopper2.3 directory and type:

patch -p1 -d . < /path/to/qpopper2.3-dce-0.5.diff


This patch has only been tested under Solaris 2.5/Transarc 1.1. If you want
to use this patch with a different vendor's DCE, you will need to edit
the appropriate makefile for your system, add the AUTH_DCE define, and
the correct libraries for your OS. You can refer to make.solaris2 as an
example.

After patch installation, the Solaris makefile by default includes the
HOMEDIRMAIL option to serve mail from a user's home directory. If you
don't want to serve mail from home directories, you need to remove this
option. If you do, you might want to edit pop_dropcopy.c to change where
in a home directory qpopper looks for mail, and change POP_TMPDROP in
popper.h so the server doesn't store temporary copies in the system mail
directory. Please see the INSTALL file in the qpopper distribution for
more details.


If your OS doesn't support DCE as a naming service, you will need to
replicate your registry in local files for qpopper to work. Solaris
users can install my nss_dce package to integrate DCE into the Solaris
naming service switch:
