[Openswan Users] could not understand problem guess i am going to loose my job

[Randy Burton]

I ran into and solved a very similar problem today - I was just using 
PSK as a temporary proof-of-concept solution and kept getting messages 
that it couldn't authenticate the user.  I found a blurb on some web 
page (not sure I recall where) that said to drop your ipsec.secrets PSK 
entry down to:

    : PSK "thisisnowmypass"

I didn't have time to fiddle around and figure out why my "192.168.1.1 
%any" part of it was making problems, but as soon as I reduced that 
entry, the PSK exchange succeeded on the first try.  Might be worth a 
try, then work backwards...
