problems with encryption_scheme in radiusd.conf file

[DilipSimha.N.M]

hi,

in the radiusd.conf file... under modules/pap

encryption_scheme variable can be set to any value, and has no effect!!!
what is it used for???

i tried....
encryption_scheme=clear

and put in users file:
netd     Crypt-Password = 12NKz5XM5JeKI
           Service-Type = Framed-User

but this also works!!!!

how can encryption-scheme=clear allow crypt passwords???
(so if it supports all methods, then what is the need of this variable?)
