I have started maintain a number of websites that are all authenticated using openam SSO. However when one of our users sets a persistant cookie (DProPCookie) it doesn't always work.
Repro scenario is:
- Login to openam, setting the persistant cookie
- Restart browser (to clear session cookies)
- Go to site A, user is logged in automatically because of persistant cookie
- Go to site B, user is presented a login page (they should be automatically logged in).
After step 3, if I delete the iPlanetDirectoryPro cookie from my browser I can login to site B fine (using the persistant cookie). It seems that the iPlanetDirectoryPro cookie generated from Site A when the DProPCookie is set doesn't work on Site B.
Note that I have tried with various permutations of Site A and B and the scenario is the same in each case.
I'm quite new to openam so any hints as to how to debug this would be great or if I'm missing something obviously going wrong please do let me know.
Thanks in advance.
EDIT:
I have subsequently discovered that the iPlanetDirectoryPro cookie returned when authenticating using the DProPCookie isn't working. So thus has nothing to do with cross domain.
- Login to openam, setting the persistant cookie
- Restart browser (to clear session cookies)
- Go to site A, user is logged in automatically because of persistant cookie
- Delete all cookies except iPlanetDirectoryPro cookie
- Refresh page - asked to login
If I repeat the test but with the iPlanetDirectoryPro cookie generated by a normal login then when I refresh the page, I automatically get authenticated. (I have changed the title of the question to reflect this).
FURTHER EDIT:
Turned up debugging - am seeing this exception in the logs:

A quick scan through the openam code - it appears that we are not getting a username here in AMAccountLockout.java:264:
public boolean isLockedOut() {
// has this user been locked out.
String userDN = loginState.getUserToken();
return isLockedOut(userDN);
}
