The parameters that can be configured are: password length, password valid duration, number of special characters, number of capital letters and number of digits.

Backup/Restore: Run Time Limitation for Backup Jobs
Occasionally it is useful for backup jobs to be skipped or canceled automatically. From this version four different Run Time Limitations can be set for backup strategies: Max start delay specifies the maximum delay between the scheduled time and the actual start time for the job. Max wait time specifies the maximum allowed time allowed for a job to wait for a resource, for example waiting for a tape to be mounted. Max run time specifies the maximum time allowed for a job may run, calculated from the time when the job actually starts. Max duration specifies the maximum time allowed for a job may run, calculated from the time when the job was scheduled to start. Each parameter can be set in the dialog Settings → System Configuration → Backup → General.

Issues Fixed in this Version
Zarafa Groupware: High System Load When Sending An E-Mail To All Users
Emails sent to many users on a Collax system delivered by Zarafa Groupware caused high system loads and the Zarafa service to quit afterwards. This update changes the email delivery method in Zarafa to lmtp (local mail transfer protocol). This fixes the problem and emails can be delivered to all system users.
E-Mail: SMTP Auth for User from Active Directory
If users are authenticated via Active Directory and emails are sent from an external network, like internet, with the SMTP Auth method, authentication failed because a PAM file in the system was incorrect. This file is now corrected in this update: User authentication via Active Directory with the SMTP Auth method will now work.
Collax E-Mail Archive: Mount E-Mail Archive, Comma in Password
The mounting an email archive found in a network share failed if the password of the share contained a comma.
Collax E-Mail Archive: Restore Data of Mail Archive Without Installed Module Collax Mail Archive
If data from the email archive was restored on a new Collax system and that system had not installed the Collax Mail Archive then specific owner permissions for /var/lib/mailarchive/volumes were not set correctly. That led to repeatedly creating email archive volumes. This is now corrected and the permission for the directory will be set when installing the Collax Mail Archive.
Collax E-Mail Archive: Encoding of Forwarded E-Mails
The character encoding of a forwarded email from the email archive was not correct. This update changes the encoding to UTF-8 and special characters and umlauts are displayed correctly within forwarded emails.
Authentication: Start of LDAP and AD-Proxy
The start of a local LDAP directory could be delayed if the server was synchronising against an Active Directory. The reason for this was the large number of LDAP log files which had to be read while starting up the local LDAP. These log files are cleaned up with this update. This means the LDAP can start faster.
Authentication: Improvements of Active Directory Integration
In this update many improvements will be implemented for the integration of Active Directories. These improvements deal with email addresses, active monitoring of the AD proxy and clean up of imported AD objects when leaving an AD.
System Management: Active Monitoring of LSI Megaraid Controller
This update corrects the monitoring and email notification for Megaraid-Controller from the vendor LSI. The active monitoring checks the status of Raid systems.
Zarafa Groupware: Zarafa Update for Collax Server Version 5.0.32
From this version Zarafa Groupware is available as an integrated Collax module. This means that the Zarafa ISV application is replaced by the module. For this reason Zarafa Groupware is going to be registered with a Collax license. This update results in the upgrade of Zarafa to Groupware 7 automatically.
Zarafa Groupware: Zarafa Web Access Mobile cancelled in ZCP 7
From version Zarafa 7 the Zarafa Web Access for mobile devices is not available any more. To connect mobile devices to Zarafa, z-push can be installed and used.
Security: Changing Password shows Error Message in Windows XP
Only if a Collax server is acting as a PDC and providing password policies: If a user password is changed with Windows XP a false-positive error message will be displayed even the password had been changed correctly.
Backup/Restore: First Backup Will As Full Backup
Because the backup system is going to be updated, the first backup scheduled after the update to version 5.5 will be a full backup. This will happen even if the next backup is meant to be an incremental backup.
