[ovirt-users] [3.6] API - Internal Server Error

After some time, API stopped work. When I try to run any request I see only "Internal Server Error" and the log like this: 2015-11-18 17:53:05,634 ERROR [org.ovirt.engine.extension.aaa.jdbc.binding.api.AuthnExtension] (default task-314) [] Unexpected Exception invoking: AAA_AUTHN_AUTHENTICATE_CREDENTIALS[d9605c75-6b43-4b00-b32c-06bdfa80244c] How can fix it? -- Maksim Naumov Hitmeister GmbH Softwareentwickler Habsburgerring 2 50674 Köln E: maksim.naumov(a)hitmeister.de www.hitmeister.de HRB 59046, Amtsgericht Köln Geschäftsführer: Dr. Gerald Schönbucher
