I seem to have an issue with some username changes, I can see the new changes have transferred in from AD correctly and the destination user updating. However,
when a user recieves a task they are unable to open the form with an error referring to their old username.
Does anyone have any idea how to get round this?
What error is currently being thrown? Are you perhaps able to attach a screenshot/stack trace?
The Windows LSA Cache may hold on to the old username when it is changed in Active Directory, although there is not yet enough information to say this is the cause. But perhaps related to this:
