Can't log out, link just reloads page

Hi all,

I have a very barebones installation of OOD on CentOS 7 authenticating via DEX to an LDAP directory. Everything seems to work great except that the “log out” link in the upper right just… doesn’t do anything. If you click it, the page reloads and you are still logged in. Eventually I guess your session cookie expires and you just get a generic server error trying to do anything and the page won’t load anymore. But, if you open an incognito window, everything appears to be fine and you can log back in no problem with the same user or a different one.

I think I recall this is some kind of known issue, but I can’t find mention of it in here… anyone know how to deal with this? Thanks!
