GUI: Network Groups
Within this release network groups can be used. Network groups offer a new configuration approach. In the past, permissions have been configured using the user groups. Network and service permissions have been used in one group together. From now on network groups are created and can be used seperately. All services on the Collax Server whose permissions are assigned exclusively on the basis of an IP address from now on use network groups. If a permission is set, the respective network port is opened in the firewall for the associated networks or hosts.
GUI: Transparent user and network permissions
Within this release permissions for users and permissions for networks are differentiated. So there are user groups and network groups from now on. A number of network groups are created by default. The Internet group contains the “Internet” network as member, i.e. all IP addresses outside the local network ranges. Thus, all permissions granted over this network group apply to all computers anywhere on the Internet.
There are various input boxes where ip addresses have been used in the previous version. Within this release the usage of ip addresses has been renewed. Collax Server V7 now uses host-elements. The term “host” refers to individual computers that are known to the Server. A host as an existing element is needed for various settings regarding the services. Host-elements replace the input boxes for ip addresses.
GUI: Clean-up form history and popups
In the dialog “Clean-up” in the menu Status->Toolbox->Clean-up it is possible to remove the browserdata saved by the GUI. Its the form history and the form popups.
Authentication: Status of Active Directory Integration
Within this update the integration of Collax Servers into Active-Directory environments have been extended. An additional field with extended runtime information is displayed. Therefore the Active-Directory-Proxy must be activated. Information regarding the connected Domain-Controller (DC) and other useful information is displayed.
Authentication: Importable Active Directory Groups
For groups from the Active Directory management to be displayed, the system must have joined an Active Directory as member, and the Active Directory proxy must be activated on the system. The listed group can be integrated in the local policies after these have been included in the management. The users of the AD groups will continue to be managed via the Active Directory and are not part of the local system. Within this release some improvements have been implemented.
Authentication: Synchronisation with Active Directory
Until now, the synchronisation of directoy objects in Active-Directory (AD) environments stopped, when the Domain Controller wasn’t reachable during a configuration activation. The synchronisation worked only after a restart of the service or another config activation. The behaviour has been improved within this release through frequent runtime checks if the server is reachable again.
