+fixes:

+    There was a bug (bug#1964509) in dynamic credentials creation where
+    project credentials with different roles are created with the new
+    projects. Credential of different role of projects must be created
+    within the same project. For exmaple, 'project_admin', 'project_member',
+    'project_reader', and 'primary', credentials will be created in the
+    same projects. 'alt', 'project_alt_admin', 'project_alt_member',
+    'project_alt_reader' will be created within the same project.
