Crowd 2.7.0 crashes when running behind Apache mod_proxy with SSL

Christian Schlaefcke
Christian Schlaefcke Sep 25, 2013

Hi,

I just upgraded to crowd 2.7.0 and encounter a strange problem since that.

When I start crowd everything looks fine. When I access the crowd web interface I can log in and browse the different sections (applications, directories, etc.). When I enter the details of a certain section (e.g. the crowd-application in the applications section) the browser requests hangs and ends up in a "502 Proxy Error".

The logs are quite noiseless about this:

I already searched at the available Atlassian resources and google indeed - unfortunately without success :-(

Any help would be very appreciated!

Christian

There are some known issues with Crowd 2.7 when tokens are stored in database. See https://jira.atlassian.com/browse/CWD-3697 and related tickets.

The workaround is to store them in memory. See https://confluence.atlassian.com/display/CROWD/Session+Configuration#SessionConfiguration-token
