Наткнулся на проблему ...
На Debianе есть сервер DHCP пропадченый под LDAP, лдап работает без проблем заходит клиентом и т.д.
А когда запускаю DHCP - вот:
netup:/etc# /usr/sbin/dhcpd3        
Internet Systems Consortium DHCP Server V3.0.4
Copyright 2004-2006 Internet Systems Consortium.
All rights reserved.
For info, please visit http://www.isc.org/sw/dhcp/
Error: Cannot login into ldap server localhost:389: Invalid credentials
Configuration file errors encountered -- exiting

Вот dhcpd.conf

#
# DHCP Server Configuration
#   see /usr/share/doc/dhcp*/dhcpd.conf.sample
#
                                                                                                                                    
ldap-server     "localhost";
ldap-port       389;
ldap-username   "cn=resman,ou=ressources,dc=netup,dc=grin,dc=by";
ldap-password   "{SSHA}LmgvcZP7zlKZTc5Xj52KDwpeiIyW+iNi";
ldap-base-dn    "ou=DHCP,ou=ressources,dc=netup,dc=grin,dc=by";
ldap-method     dynamic;
# ldap-method   static;
ddns-update-style ad-hoc;
ldap-debug-file "/var/log/dhcp-ldap-startup.log";

Хотя делаю ldapsearch -D "cn=resman, ou=ressources, dc=netup, dc=grin, dc=by" -W -x -d 25

и всё гуд

netup:/etc# ldapsearch -D "cn=resman, ou=ressources, dc=netup, dc=grin, dc=by" -W -x -d 25
