SPS inband gateway authentication error in SSH connections

Hello,

i'm trying to connect to my Linux server using SPS 7.1.1 for the inband gateway authentication and the credential injection. I have created a non transparent connection to the server, i have added the active directory in the ldap server section, and i have configured the connection to use the ADGateway authentication policy. When i start the connection from the SSH client, SPS correctly ask me for the gateway user i want to use, but when i enter the password something goes wrong and he continues to prompt me to insert the gateway user password.

Am i doing something wrong? What kind of problem could it be?

Thank you,

Samuele
