OBIEE 11g Security Bug

Installed OBIEE 11.1.1.5 on Windows 2003 R2 x64; setup AD LDAP via Oracle doc ID: 1273961.1 after setting up web catalog security via application roles had issue were one time user would got security that allowed them access to the items the next time they logged in they didn't have access. Checked the users "My Account" both times the same roles were assigned. Hmm...put in SR with Oracle found out there is a bug that caused this. Was given Patch 12393459 and it fixed the issue.
