We need to make an LDAP query to the LDAP database, We want their Radius to check if this authentication is alright.
The single authentication works between Radius server and Notes LDAP since the connection between the LDAP and the radius is established the first time with an authentication, and this works ok. But when the connection is established and authenticated, if the radius has to make more queries to the notes ldap in bindname mode, the LDAP send without problems the information (we sniffed all the communication) but with an encrypted password, so when this information arrives in the Radius, it does not match since the RAdius has the password in clear text.
They could try to make single connections authetnticates, but this method consume resources of the notes servers since it need to negotiated several connections and not only one connection in whitch it makes all the queries.
