Dear Alan,Ivan and all, I have updated my FreeRadius version 2.0.5 Installed on SLES 10 SP2 through CVS. Now when I authenticate with a User i didn' get a BackTrace. But when I try to Authenticate against Openldap I see this Trace with Memory Map after Server returns back the result. Do I need to Install latest version of FreeRadius to be compatible with the CVS update for my current version.
