Re: Search base between 2 OU in iRedmail with AD integration

Oh, here's another way if you cannot config AD to allow search from root dn (dc=example,dc=com): Uses LDAP query files in Postfix instead of one, and use different base dn (ou=Employees, ou=Parttime) in them. For example:

Original one:

smtpd_sender_login_maps = proxy:ldap:/etc/postfix/ad_sender_login_maps.cf

We now use two query files instead:

smtpd_sender_login_maps =
    proxy:ldap:/etc/postfix/ad_sender_login_maps_employees.cf,
    proxy:ldap:/etc/postfix/ad_sender_login_maps_partime.cf

Update ad_sender_login_maps_employees.cf to use ou=Employees as search base dn:

search_base     = ou=Employees,dc=example,dc=com

Update ad_sender_login_maps_partime.cf to use ou=Parttime as search base dn:

search_base     = ou=Parttime,dc=example,dc=com

That's all. And replace other LDAP queries the same way.

Again, please try to configure AD to allow searching from root dn (dc=example,dc=com) first.
