Creating a user group with long ID failed with "value too long for column"

I tried to create a user group in app admin with a very long id.

On Save the following Database error occured, stating, that the DB column is limited to varchar(64):
Server Error : ENGINE-03004 Exception while executing Database Operation 'INSERT AuthorizationEntity[b4a1773d-e6f7-11e6-aa20-18dbf21c9f0c]' with message ' ### Error updating database.
