Diagnosing the problem

Resolving the problem

1. Create a new Security Role for mediaGalleryAdmin by going to:

Security > Global security > Java Authentication and Authorization Service > JAAS - J2C authentication data.

Select New and set the alias to mediaGalleryAdmin, and add an admin user who can authenticate and exists in the Profiles database.

2. Then add the user from the mediaGallery j2c role, to the Security Role for admin in the Files Application.

3. Also replace the connectionsAdmin role with the newly created mediaGalleryAdmin role to the j2c property in the events-config.xml

<property name="j2calias">mediaGalleryAdmin</property>
