Hi, I have a server A proxying requests to server B (having LDAP enabled), and a client C requesting A. When I try to connect from A to B with radclient it works. Logs say : Login OK: [blabla2] (from client rad1-eee port 0) When I try to connect from C to A : Login incorrect (ldap: Bind credentials incorrect: Invalid credentials): [blabla2/?Q?#%?????)[~???dW???ŝ7?g-m?[˵] (from client rad1-eee port 0) I don't get why the credentials differ while proxying, which conf file should I check to understand this? Is this part coming from an ldap conf problem or from radiusd.conf problem? /?Q?#%?????)[~???dW???ŝ7?g-m? Thanks for your help.
