Uninstalling OneSpan Authentication Server

Pre-uninstallation tasks and considerations

Administrative privileges

To uninstall OneSpan Authentication Server you must be logged on using a built-in administrator.

Database

When uninstalling an instance of OneSpan Authentication Server that uses an external database, the database files and data inside will not be removed.

When uninstalling an instance of OneSpan Authentication Server that uses the embedded MariaDB database server, the database files and data inside will not be removed. If database encryption is enabled, the data-at-rest encryption key and certificate files will not be removed and remain on the disk as well.

If you uninstall OneSpan Authentication Server via the OneSpan Authentication Server Setup Utility, you will be prompted whether to automatically remove or keep the existing database files and data-at-rest encryption key and certificate files used by the embedded database. If you choose to keep them, you will need to back up and delete them manually, before reinstalling OneSpan Authentication Server.

Removing schema modifications

The dropschema command in the dpdbadmin command-line utility can be used to remove all schema modifications from the database, deleting all data relating to OneSpan Authentication Server (see dpdbadmin dropschema).

Firewall ports

If ports have been opened on the firewall during installation, they must be closed after uninstallation.

For more information, see Open port numbers on firewall.

Uninstalling OneSpan Authentication Server

To uninstall OneSpan Authentication Server

1. Terminate any running OneSpan Authentication Server applications, e.g., Configuration Utility.

2. Open the control panel, usually via Start > Control Panel and select Programs and Features.

3. Select OneSpan Authentication Server and click Uninstall.

   OneSpan Authentication Server is uninstalled.

4. Depending on your initial installation, you may also need to remove additional packages installed along with OneSpan Authentication Server:

   • OneSpan Authentication Server Web Administration Service

   • Apache Net-SNMP

   • MariaDB (Caution!)

   • MariaDB ODBC Driver 64-bit

   • DBeaver database tool

5. When uninstalling the embedded MariaDB database server, you are prompted whether to remove or keep the existing database directory:

   • If you do not intend to keep the existing data, select Remove data when uninstalling MariaDB; the default database folder (data) will be deleted.

     If you have initially enabled database encryption, you also need to delete the folders in %PROGRAMDATA%\VASCO\IDENTIKEY containing the certificates and encryption keys, i.e. cert and encr.

   • If you intend to use the data after reinstalling, select Keep data when uninstalling MariaDB; the default database folder remains on the disk.

     Create a backup copy of the database folder and—if you have initially enabled database encryption—the certificate and encryption key folders and delete them afterward, i.e. data, cert, and encr. After reinstalling MariaDB, you can restore the folders and migrate them to the newly installed MariaDB database server.
