The vendor has published 2 unique mention(s) for this bug: 1. When the recent change was made to add the ability to define read only admin groups, the powershell SDK had a bug whereby it was never possible to specify that read only access was required when grating a group admin access. 2. If you use the IsReadOnly parameter with the New-PvsAuthGroup or Set-PvsAuthGroup cmdlet, a database error might occur; use the Grant-PvsAuthGroup cmdlet to set the read-only state of an authorization group instead.
