I anticipate that this release will become final/stable in the coming week. There might be a few more documentation additions/changes, but otherwise it should be solid and complete.
We've got some last-minute (yet significant) updates to LDAP before the final 5.4.0 release. This release candidate also has some more documentation, and should correct a problem with having incorrect owner/ group/permissions when doing `make install-strip`.
Michael Bowe - Code fixes and documentation work for LDAP module. Incl updated README.ldap, vldap.c, vldap.h, ldap/slapd.conf, ldap/vpopmail.ldif.    - Rewrote the README.mysql based on my web based guide. - Documentation tweaks for README.pgsql, README.roamingusers.
Tom Collins - Remove unused var (cp), change random/srandom to rand/srand in vpopmail.c to remove compiler warnings. - Fix Makefile to use correct owner/group/permissions for install-strip. - Fix configure to indicate that --enable-auth-logging is default.
