maybe you are referring to the reauthentication request happening in the administration area?

PS. upgrade to 1.1.6 now, really...

giallu,
No - this is not in reference to reauthentication request in the administration area.

I log in to mantis , get logged in, go to 'View Issues' page , close my browser and re-visit same page -> now I am logged out.

Yes, we will be upgrading to 1.1.6 soon. BTW, does 1.1.6 solve this problem?

1.1.6 has some very important security fixes you should really have. I am not sure if that will fix your problem (probably not) but we need to check anyway the latest version because an eventual patch has to be applied to the 1.1.6 codebase.

It would be even more useful if you could determine if the latest alpha release suffers from the same problem.

Thank you in advance

this problem still exists in 1.2.0

logging in with "permanent login" => visiting a page within mantis => closing browser => revisit site after some time => redirection to login page

which means that cookies have been disabled? are cleared out when closing the browser?

@yw84ever:
Yes, the problem is MANTIS_STRING_COOKIE. Normally, i do a permanent login, which sets the expiration of this cookie to 1 year. But if i visit the management section and have to reauthenticate, the cookie changes its type to "session".

This could be a duplicate of 0011680... check your PHP session garbage collection timeout?

Assuming this issue is a case of incorrect PHP session timeouts as per 0011680.
