There is some kind of timeout session between PPM and LDAP or something similar to the timeout session of PPM? We are having some issues with users using LDAP authentification method. Users can log into the system, but time to time when they are trying to create a project, at the moment they sendthe project ,they are force to log again into PPM and after that a "500 unknown server error" appears.
Thanks for your answer, this might be the reason. Currently this is happening on a 9.22 environment but in HP Support says it only hapens on 8.xx and 9.10 version. Do you know if this version is affected also?
