I have it working on my machine with vpopmail-5.4.7, courier-authlib-0.50.20041103 plus the attached patch, and sqwebmail-4.0.7.20041103

If you want to run with an older version, try just removing the following line from authlib/preauthvchkpw.c and recompile:

auth.sysusername = userid;

That may (untested) be sufficient to fix the problem for you.

Regards,

Brian.
