Hi Zhang, Hi all,
I have a server mail  connect to a remote ldap server (both servers are on iredmail ).
I can connect over my Roundcubemail  correctly but i have problem to connect over sogo.
Here is the error related in /var/log/sogo/sogo.log
SOGoRootPage Login from  for user 'user@domaine.tld' might not have worked - password policy: 65535  grace: -1  expire: -1  bound: 0
I have configured the sogo.conf under /etc/sogo for remote ldap:

// Authentication using LDAP

    SOGoUserSources = (
        {
            // Used for user authentication
            type = ldap;
            id = users;
            canAuthenticate = YES;
            isAddressBook = NO;
            displayName = "LDAP Authentication";

            hostname = "ldap://ip-remote-ldap:389";
            baseDN = "o=domains,dc=xxx,dc=tld";
            bindDN = "cn=vmail,dc=xxx,dc=tld";
            bindPassword = "password";
            filter = "objectClass=mailUser AND accountStatus=active AND enabledService=mail AND enabledService=sogo";
            scope = SUB;

Thank's for help
