Ey guys,

I'm trying to get Kerio Mailserver working together with Active Directory but the connection doesn't work.
I'm getting the following error when I try to connect to my AD:

Directory server:
The schema extensions haven't been found on the LDAP server:
the connection won't be functional.


The strange part is, I did install the Kerio Active Directory Extensions (6.2.2) and I can see the new tabs in Active Directory.
I just can't get the connection to work.

I did allot of research but I just can't find the sollution.
There were some dudes on this forum with the same question but never got an answer also on other forums no sollution at all.

Can someone help me with this problem?

BTW: AD is working 100%, nothing wrong with it

Two things I can think of:

1. Did you run the KMS AD extension on your schema master? There are two parts to the AD extension - the UI extension, and the schema extension. Seeing the tabs in the AD console means the UI extension installed, but doesn't necessarily mean the schema was updated.

2. Try setting KMS to look at the schema master.

Okay, so thats the problem. :)
To be honost I just started with Active Directory so I still need to learn allot.
But how do I install the schema extension?
I just installed the extension with my admin account that's domain admin (and admin of everything else :P).

We've all been there.. you have to start someplace, right.

To determine which machine is the Schema Master, click Start -> Run, type MMC and hit enter. Click File -> Add/Remove Snap-in. In the Add/Remove Snap-in window, click Add, find 'Active Directory Schema' in the list and click Add, then Close, then OK in the Add/Remove Snap-in window.

Now, under the Console Root in the MMC, you should see the Active Directory Schema tree. Right-click on the top level of that, and click Operations Master. That screen will tell you the current Schema Master for your AD infrastructure. You'll have to run the Kerio AD extension on that machine to have the schema updated.

I can't remember off the top of my head if a domain admin will have the correct privileges to update the schema. I seem to remember access denied topics coming up before in the forum. You may need to be added to the schema admins group. If you get an error when you try to install the schema extension, have yourself added to the schema admin group and try again.

Thanks for your help sedell, I appreciate it very much! :)
But the problem is that I don't see the "Active Directory Schema" in the options menu.
I added a screenshot so you can see it yourself.

Just ignore that, already found out that you can install it with "regsvr32 schmmgmt.dll". :)

Okay I got that Active Directory Schema to work in the console, I checked if it was the right machine and it was (duh... I only use 1 server).
I added my admin to the new Schema Admins group, reinstalled the extension and still it doesn't work. :(

New Schema Admins group? You didn't create one, did you? There should be a built-in Schema Admins group that already has the correct permissions set up.

Are you getting an error when you try to install the schema extension?

Yeah...I noticed that there is a new group called "Schema Admins".
I didn't make on, the install/config of "Active Directory Schema" made that one I guess.
The only thing I did was made the admin member of that group.
And no, I didn't get a error with the installation of the extension.
