This object specifies how the system processes the CHAP on a
target PPP connection:
'refuse'
This option specifies that the system should refuse CHAP
requests from peers of a target PPP connection.
'callin'
This option specifies that the system should only refuse
CHAP requests for incoming calls on a target PPP
connection. This option is only relevant if the
'refuse' option is set to '1'.
'wait'
This option delays CHAP authentication until after the
peer of a target PPP connection has authenticated itself
to the system.
'encrypted'
This option specifies that the value specified by the
corresponding instance of cdtPppChapPassword is already
encrypted.
This column is valid only if the 'chapOpts' bit of the
corresponding instance of cdtPppValid is '1'.
