Configure Certificate Authority Web Enrollment (CAWE) for use with a Group Managed Service Account (gMSA).
For security reasons, it may make sense to operate the CAWE with a Group Managed Service Account (gMSA) instead of a normal domain account. This option offers the charming advantage that the password of the account is changed automatically, and thus this step does not have to be done manually, which is unfortunately forgotten far too often.
