Authentication: Synchronisation with Active Directory

Whenever an object and its attributes change in an Active Directory Environment with multiple Domain Controllers (DCs) its Update Sequence Number (USN) is incremented. The Active Directory Proxy (AD-Proxy) then synchonizes. In environments with multiple DCs these USNs differ per DC. Thereby it could happen that the USN was lower than the saved one, resulting in no synchronisation. Within this update the mapping of USNs per DC is beeing saved in a sequence file so that all users and groups are synchronized.

E-Mail: AMaViS and strict HELO settings

With the option “HELO identification required” set to the value “Strict” when using AMaViS (A Mail Virus Scanner) no emails could be sent. This is fixed within this update, email will be sent, if the option is set to “Strict”.

Collax Web Security: Web Proxy does not start, bungled configuration

For certain Web pages, header lines need to be removed in order for these pages to be displayed correctly when using the Web proxy. Otherwise, a white browser window would be displayed instead of the content. By using the field Disable transfer encoding in the Tab “Advanced” the domains of the Web pages can be entered. If the configuration was bungled due to double occuring entries, this resulted in the Web-Proxy-Service being unable to start. There will be a fix in this update recognizing double entries.
