[Samba] FW: making BDC samba + ldap server

Sun Feb 27 05:20:10 MST 2011

Hi

Well, all is mounted using openldap,. and I’m thinking how to reduce the
traffic net. My doubt is if I use a slave ldap server inside mail server
when users go to change their password not produce problems synchronizing.
For the rest of points you comment all server has the same version of
openldap and I use postfix and samba 3.3.2 openldap is 2.4

I continue testing, thanks for all your time, this list is very friendly
with me :-)

Thanks And Best Regards
