What are the steps to upgrade to QAS 4.x ?
We recommend upgrading in a test environment first before upgrading to production.
1 - Download the latest from https://support.oneidentity.com/authentication-services/download-new-releases
Once download you can run install.sh -upgrade. The systems should be rebooted after the upgrade or all services that interact with Authentication Services should be restarted.
2 - Determine what AD attribute you are currently using as your logon attribute. If your login attribute is not sAMAccountName, then you will need to modify the vas.conf file to set it before upgrading.
For example if you were using the 3.5 default logon attribute which was userPrincipalName. Before upgrading do the following command on your unix and mac clients to set your logon attribute in the vas.conf: /opt/quest/bin/vastool configure vas vasd username-attr-name userPrincipalName
