ms6ag (ms6ag) asked a question.
We have a requirement for CA PAM application that it should use a DN as a username. We mapped Okta attribute that holds DN information, to CA PAM user name but when we assign users to the app and Okta attempts to populate app's username we receive this error:
Please review the form to correct the following errors:
credentials.userName: The field is too long
Apparently DN is too long to fit in the username field.
When I check CA PAM profile, username field's length is less than 100 but I am not able to modify that as it is a Base attribute.
Is there any way to make the username larger or is there another way to circumvent this issue?

It is not possible to extend an application username field.
Is this is a custom expression? If so it seems the formatting would need to be entered properly.
