the value of "passdb backend" is a freeform text value, whose allowed values
are extended by the addition of plugins.  It's improbable that testparm will
vet these values.

Christian referred to the upstream samba changelog, not to the Debian
package's changelog.  The upstream changelog isn't included in the Debian
binary packages.

No, it's not important functionality removal.  The 'guest' backend was an
obsolete no-op before sarge's release.  So a silent upgrade is the correct

If there are cases where the guest value is not being automatically removed
when it should be, we want to know about that so we can fix it.  What
version were you upgrading from?

Yes, as I mentioned the 'guest' backend is long obsolete.

Steve Langasek                   Give me a lever long enough and a Free OS
Debian Developer                   to set it on, and I can move the world.
