>Description:
	isppp and isdnd appear to stomp on (some) option fields.

>How-To-Repeat:

[hf@jump] /etc/isdn # ipppctl ippp0 myauthname=FOO hisauthname=BAR
[hf@jump] /etc/isdn # ipppctl -v ippp0
ippp0:  phase=terminate
        myauthproto=chap myauthname="FOO"
        hisauthproto=chap hisauthname="BAR"
        lcp timeout: 0.800 s
        idle timeout = disabled
        max-auth-failure = 5
[hf@jump] /etc/isdn # ipppctl ippp0 myauthname=FOO 
[hf@jump] /etc/isdn # ipppctl -v ippp0
ippp0:  phase=terminate
        myauthproto=chap myauthname="FOO"
        hisauthproto=chap hisauthname="(null)"
        lcp timeout: 0.800 s
        idle timeout = disabled
        max-auth-failure = 5
[hf@jump] /etc/isdn # ipppctl ippp0 hisauthname=BAR
[hf@jump] /etc/isdn # ipppctl -v ippp0
ippp0:  phase=terminate
        myauthproto=chap myauthname="(null)"
        hisauthproto=chap hisauthname="BAR"
        lcp timeout: 0.800 s
        idle timeout = disabled
        max-auth-failure = 5
[hf@jump] /etc/isdn #

This results in the client failing to chap authenticate after ten
retries that produce the log entry

Oct  2 18:21:39 jump /netbsd: ippp0: chap starting without my name being set

Setting the {my,his}auth{name,secret} in /etc/isdn/isdnd.rc makes no
difference.

	None, sorry.
