Dear SOGo-Team,

we would like to prevent the SuperUser from being found in the calendar subscription search.

We managed to prevent that user from being found in the shared address book.
To this end the sogo.conf configuration has two sections in SOGoUserSources for searching in ldap.

SOGoUserSources = (
        {
id = "ldap_auth";
type = ldap;
...
canAuthenticate = YES;
isAddressBook = NO;
        },
        {
id = "ldap_addressbook";
type = ldap;
...
canAuthenticate = NO;
isAddressBook = YES;
filter = "(NOT mail='')"

But this approach does not the prevent the SuperUser (characterized by not having an e-mail address) being found in the subscription search.

Is there a way to hide that user?

Thanks
Kind regards
