Unable to login to the console.

 Hi,

weblogic user is getting locked every 30 minutes from Nov 3, 2013 9:31:24 PM  until now. Strange pattern is that it gets unlock after 30 minutes which is standard lockout expiry time but right after that it unlocks itself.  Look at the logs below:

<Nov 3, 2013 9:31:24 PM UTC> <Notice> <Security> <BEA-090078> <User weblogic in security realm myrealm has had 5 invalid login attempts, locking account for 30 minutes.>

<Nov 5, 2013 9:08:08 AM UTC> <Info> <Security> <BEA-090067> <User lockout expired, unlocking user weblogic in security realm myrealm.>

<Nov 5, 2013 9:08:08 AM UTC> <Notice> <Security> <BEA-090078> <User weblogic in security realm myrealm has had 5 invalid login attempts, locking account for 30 minutes.

//Thanks,

Grandhi.
