Is there a character limit when creating a new CORE User ID? What are the requirements for CORE User IDs?
The CORE User ID maximum length is 16 characters, and they all must be lowercase. For requirements when completing a UDOC you will want to review the CORE Access Policy which can be found on the Security and Workflow Policies page.
If the CORE User ID will exceed the 16 character limit, you will want to truncate the User ID.
