AEM unable to login

Hi Experts,

We are running AEM 6.0 with SP2. After a recent restart of one of our publish instance, we are no longer able to login with admin credentials.

We keep getting the following error in the logs:

 

16.10.2015 13:49:40.262 *WARN* [qtp2074601335-30] org.eclipse.jetty.servlet.ServletHandler /libs/granite/core/content/login.html

        at org.apache.sling.engine.impl.SlingHttpContext.handleSecurity(SlingHttpContext.java:121)

 

Any help in this regard is much appreciated !!!

 

Thanks,

Anwar

    Correct answer to this question is to clear cookies, whatever is marked as "correct" is incorrect.

    Was there any custom implementation or other changes done to your AEM instance that may account for the changed behaviour in the token?

      Hi- Figured out that the authentication is successful. But the "login-token" cookie return by AEM is not valid.

      It is supposed to be like: login-token=4177bc3c-8d72-40e2-be47-bd6f93c1b5ae%3ad7bd26b3-cd48-4430-b7d7-d60fdecb2361_660c460ab31f8e8f%3acrx.default

      But it looks like this: login-token=117182c7-02d4-4c88-97b3-0714fa1ff3b2%3a<MISSING TOKEN>%3acrx.default

      Any idea why this could have happened and any remedies?

                Right, well after recent restart something must have happened to your system. As this exception is not the most explanatory one check earlier in the logs for more meaningful hints to what has happened and why authentication does not want to work. Thanks, Peter
