Users/Groups in the Defender Desktop login exclusion list are unable to log on after upgrade to Defender 5.8 (4276205)

Users/Groups in the Defender Desktop login exclusion list are unable to log on after upgrade to Defender 5.8

The Users or Groups listed in the Defender Desktop login exclusion list are unable to log on after upgrding to Defender 5.8
This does not affect users who are using Defender tokens.

This issue occurs when the DNS domain name does not match the Netbios name and you are using Group policy for the exclusion list.

For example:
DNS domain name:  QADefenderDC.domain.com
NETBIOS name: QADEFDC

Before upgrade form 5.7 to 5.8:
DNS domain name is being added with group.
(QADefenderDC\NonDefenderGroup)

After upgrade from 5.7 to 5.8:
NETBIOS name is being added with group. 
(QADEFDC\NonDefenderGroup)

WORKAROUND:
Edit the group policy for the exclusion list after upgrading to version 5.8

Re-add the Users and groups to the policy.

Defect 494522 has been raised to address this issue in a future release of Defender. NOTE: After making the changes to the group policy, older 5.7 Defender Desktop login clients will not work with the new policy.
