no auth possible: 'getlogname (AUTO_PPP, read:'

[Ekkard Gerlach]

Hello, 

using gnokiid to dialing to a ISDN-getty I can't
afford authentication. Either I get 

  The remote system is required to authenticate itself
  but I couldn't find any suitable secret (password)
  for it to use to do so.
in /var/log/messages (server side)

or: 

  10/18 12:09:00 yI1   getlogname (AUTO_PPP), read:

in /var/log/mgetty.ttyI1 (server side). 

But username and password are definitely in /etc/pap-secrets
(chap excluded)!! Using noauth in /etc/mgetty+sendfax/login.config
(server side) I get a connection. But auth is necessary. 


my /etc/ppp/peers/demon-gnokii:
/dev/gnokii 115200
modem crtscts defaultroute
connect 'chat -v ABORT BUSY ABORT ERROR ABORT "NO CARRIER" "" AT OK-AT-OK 
ATZ OK ATS35=0 OK ATD07998399999 CONNECT'
user otto
#noauth
#connect-delay 5
# the above seems critical. The standard delay is 100. With that only half
# of the tries got a connection. With 5 the results are much better,
# but still not 100 %
mtu 296

and on server side:
===================
/etc/mgetty+sendfax/login.config:
#/AutoPPP/ -     a_ppp   /usr/sbin/pppd noauth

any ideas?
