[SOGo] LDAP address book not visible

["Roman Smid"]

Hello,
I'm trying to add a LDAP global address book to my SoGo 3.1 installation on
Ubuntu server, but with no luck. I want to use it only as an address book,
not for authentication, which is done using MSQL and working well. I have
added

  SOGoUserSources = (
    {
      type = ldap;
      CNFieldName = cn;
      UIDFieldName = uid;
      IDFieldName = uid; // first field of the DN for direct binds
      bindFields = (uid, cn); // array of fields to use for indirect binds
      baseDN = "ou=admini,dc=iba,dc=muni,dc=cz";
      bindDN = "cn=admin,dc=iba,dc=muni,dc=cz";
      bindPassword = "secret";
      canAuthenticate = NO;
      displayName = "Address book";
      hostname = ldap://127.0.0.1:389;
      id = adresar;
      isAddressBook = YES;
      scope = SUB;
      userPasswordAlgorithm = ssha;
    }
  );

But this source does not show up in the Web UI at all  (no "Address book"
visible among Global Addressbooks).
I have enabled the LDAPDebugEnabled option, but nothing concerning LDAP
appears in the log. 
What am I doing wrong?
Thanx
Roman
