Signature: Empty Items with UCS

[A Former User]

Hey,
I am currently evaluating Kopano for use in our companie and encounter a small problem that I can’t solve by myself.

The base is UCS 4.3.2 and Kopano Core 8.6.2.1 and Kopano WebApp 3.4.19.1649.

The following items in the signature template remain empty and I find nowhere in UCS the matching attributes.

{%department}
{%office}
{%assistant}
{%phone_business}
{%phone_business2}
{%phone_fax}
{%phone_assistant}
{%phone_home}
{%phone_home2}
{%phone_mobile}
{%phone_pager}

How can I fix this? Is there a extension of the ldap-scheme or something else?

Cheers!
