Since subversion plugin 2.0 the subversion credential storage has changed. The credentials must be configured globally while the subversion access user inside a job is configured with a combobox selecting from the globally configured CI-User. After upgrading to 1.458 all credential information in all subversion based jobs are lost. This means reconfiguring more than 150 jobs.
The global configuration of credentials is confusing and time consuming. Please rollback the type of configuration of the subversion credentials to the previuos one.
