-WinCC OA 3.17 P005
-pmon running as service on the Network Service Account
-OS Auth. user administration.
When the user password has been changed in AD and the user is trying to login we get:
WCCOAui (4), 2020.10.14 11:33:34.719, PARAM,SEVERE, 0, , No permission to change password
WCCOAui (4), 2020.10.14 11:33:34.772, CTRL, SEVERE, 1/OaLogin, Unknown workstation error
(when we delete the user in WinCC and delete the OSIDs from deleted users the new(old) user is added properly when login.)
what could be the reason?
Thanks in advance.
To resolve this you need to clear the internal DP '_Deleted_Users.OSIDs' entry related to that user.
If you delete information from these datapoints on your own you will loose information. E.g. if the information is deleted and you do a historical query the user ID cannot be resolved into its name.
