The problem I specifically mentioned affects the same way a pure FreeBSD
8.0-CURRENT/amd64 installation and is identical to that what I see with
FreeBSD 7.2-STABLE.

I change the order of look-for-targets in /etc/nsswitch.conf:

previously not working and triggering issues I reported:

group: files ldap
passwd: files ldap

working after exchanging order:

group: ldap files
passwd: ldap files

This is weird! After I changed that, the first attempt issuing the
passowrd now takes 20 seconds to respond even for local users, if I hit
return for the first passwd-attempt and issuing the passd on second
attempt runs immediately towards expected login.

Intention of having first files looked up was: sometimes LDAP is dead or
we make tests and can not reach LDAP, so we need to login via local
stored users. Having first LDAP consulted makes a login a desaster:
after a minute some boxes cancel login attempt caused by timeout. That's
fun.

Even with

passwd: ldap [unavail=continue notfound=continue] files [success=return
notfound=return]
group: ldap [unavail=continue notfound=continue] files [success=return
notfound=return]

it fails. There is something wrong, not specifically with 7.2.
