bug in NSS ?

I have a problem with nss_ldap on FreeBSD.
After tranfer users from /etc/passwd to ldap directories my users cannot
send a mail via /usr/bin/mail | /usr/sbin/sendmail  program:

ldap_user$ id
uid=1000(test) gid=1000(test) groups=1000(test)

ldap_user$ pw usershow test
test:*:1000:1000::0:0:test:/tmp:/bin/sh

ldap_user$ ldapsearch -h server -b 'dc=komi,dc=mts,dc=ru' '(uid=test)'
dn: cn=test,dc=komi,dc=mts,dc=ru
cn: test
objectClass: posixAccount
objectClass: account
uid: test
userPassword: test
loginShell: /bin/csh
homeDirectory: /tmp
gecos: test
description: test
uidNumber: 1000
gidNumber: 1000
