Default setting of ALLOWDESAUTH server option updated

With IBM Spectrum® Protect Version 8.1.10, the default value of the ALLOWDESAUTH option is changed to NO. The default setting helps to enhance security by ensuring that the IBM Spectrum Protect server complies with the National Institute of Standards and Technology (NIST) SP800-131A standard.

To allow the use of the Data Encryption Standard (DES) algorithm for authentication between an IBM Spectrum Protect server and a backup-archive client, you must specify a value of YES manually.

Restrictions: The ALLOWDESAUTH option must be set to YES for the following operations:

Automatic deployment of backup-archive client versions earlier than V7.1.8 or V8.1.2
Connecting a server with a backup-archive client V6.2 or earlier
