One environment's users are Inactive and Removed Externally in a second environment using Signed License Key (SLK).
When applying an SLK to a second Qlik Sense environment, the users stored in the first Qlik Sense environment repository are synchronized to the second Qlik Sense environment. These users may be marked inactive and removed externally.
If you remove a user from one deployment, it is not removing the user access but removing the user license assignment and it would effectively remove user's license assignment from all deployments activated using the same Signed License Key.
Environment:
Qlik Sense Enterprise on Windows using Signed License Key (SLK).
Resolution:
This is working as designed. This is a synchronization for license assignments and not access rights, which is a security permission which the administrators can control at each deployment.
Contact the account management team to evaluate license use and to split/provide a new key for multiple environments.
