rad_tunnel_pwencode - Constraint on the length of Plain Text Password.

Hello, I see that we have the following check in the "rad_tunnel_pwencode(..) ". if (len > 127) len = 127; This means that we dont support encryption/decoding of password of length >127 ? Curious to know the the primary reason behind this check.. since I was in dire need of using the Radius for plaintext length > 127. Thank you in anticipation, Mahesh.
