Is this correct or not? Correct. 4.x doesn't support nsswitch.conf, so you can't use LDAP for your local machine accounts (well, not without pain). However, it does support PAM/ldap, and postfix+cyrus has been written to take advantage of that combo, so you can certainly use LDAP to provide virtual user accounts for your e-mail users. Not having your e-mail clients being able to log directly into the server would probably fall on the side of "feature" rather than "bug" in most installations. =20 > Also, if this server goes into production, then how much of a pain in=20 > the ass is it going to be to move to 5.x when it's stable? There should be an officially sanctioned route to upgrade from 4.10-STABLE to 5.3-STABLE once 5.3-STABLE is released. However, all upgrades over a major version bump are painful, and as many people on this list have said, just doing a re-install is probably your best bet. One very good reason for doing that is that 5.x has a new default filesystem type: UFS2 -- of course, it can still use UFS1, the default from 4.x; but there's no way to change a filesystem from UFS1 to UFS2 without a wipe and reinstall. If the continued reliability of this server is important to you (ie. your job or your income depends on it) then I'd be even more cautious about switching from 4.x to 5.x: since 5.2.1 came out there have been some quite significant changes to vital parts of the 5.x kernel, and it's likely to take a bit of time (even accounting for the 5.3 release process) before everything works in the way intended. Monitor the freebsd-stable@... list for news of any showstopping problems, and if you can, experiment with 5.3-STABLE on a scratch machine before attempting the upgrade. 4.10-RELEASE and the upcoming 4.11-RELEASE will be supported by the FreeBSD project for quite some time (typically 1 year after the release date), so there's no need to be in a great hurry to update everything.
