Adding a user to a user group in SIM5.0

[Mikael Rönnbäck]

When I create a user group in SIM 5, based on a Windows group, new accounts are created in SIM properly with the group access rights.

However, is there any way of adding existing user accounts to existing groups ? I cannot find the "Member of OS-group" checkbox anywhere on accounts created separately, and also if the member-of-checkbox is removed and the change is saved the account no longer seems to be possible to re-add to the group ?

Or must I delete the account so that SIM can re-create it with proper group access ?
