nsswitch - pflog problem

[skv1040]

Hi,

I have a little (I hope) problem with my FreeBSD 6-STABLE.
I had pf+pflog working fine...
I added nss_ldap, pam_ldap etc.
Everything worked fine, until reboot.

I noticed strange message:
pflogd[244]: NSSWITCH(nss_method_lookup): ldap, passwd, endpwent, not found

Nevertheless everything works.
After some experiments I discovered the message
being triggered by /etc/nsswitch.conf:
when I change "passwd: files"
to "passwd: files ldap"
message appears.

Thanks in advance
Tim
