I (re-)set up a little (working) mantis farm. Mantis version 1.2.19, Apache 2.4.10, PHP 5.6.3, Windows
Jenkins 1.599, Mantis-Plugin v0.26
This setup worked with my old Apache2.2 installation. After a new installation with Apache2.4 and updated components the connection from Jenkins to Mantis does not work anymore.
In Jenkins log I found this:
With Loggin in Mantis enabled in Jenkins-Config I clicked the "Verify" Button. The Mantis log says that my entered credentials are correct:
But the Jenkins config claims "Unable to login with the user name and password."
I don't know how to get more debug information to tear down this problem.
