Problem authenticating PAP users but CHAP OK.

Hi Sergey et al.,

My GNU Radius server is authenticating CHAP passwords OK but cannot authenticate when using PAP. 

For example when I use NT Rad Ping using PAP I get:

Oct 05 15:48:28 Auth.notice: (Access-Request 217.13.128.68 6 "harry"): Login incorrect [harry/b0w1by]

but using CHAP I get:

Oct 05 15:48:34 Auth.notice: (Access-Request 217.13.128.68 7 "harry"): Login OK [harry/b0w1by]


I have several 100 users authenticating OK except for this one AS5300 which is using PAP.

My raddb/users file looks like:

DEFAULT Group = "*LOCKED_ACCOUNT*",
                Auth-Type = Reject
        Reply-Message = "Your account is currently locked.\n\
Please, contact your system administrator\n"


## Default entry.
DEFAULT Auth-Type = SQL,
                Simultaneous-Use = 1
                Service-Type = Framed-User,
                Framed-Protocol = PPP

#DEFAULT Auth-Type = Local,
#               Password-Location = SQL


I've read the GNU press book but can't see what I'm doing wrong - any help/pointers gratefully received.

Thanks
