Zimbra Admin Extensions missing with Internet Explorer

[yogg1]

Hi

I have a really wired problem. I have a Samba domain that works with Zimbra LDAP.

The Zimbra Web UI needs 2 admin extensions for this:
zimbra_posixaccount and
zimbra_samba

The two extensions works fine with Firefox.

Now a Windows user told me that he can not add users over the Web UI to the domain. So i have tested it myself and when i connect to the Web UI with Internet Explorer the two extensions are missing

The extensions are shown in the extension list, but on the main menu they are not there. They are also missing if i try to add a new user (so i get always an error -> uid not set ...).

Tested wit Internet Explorer 8.0

Has someone the same problem? By the way how can that be?
