[Openswan Users] windows roadwarrior don't rekey!

[foren titze]

hello users,

i have set up an ipsec/l2tp tunnel with x509 certs between windowsxp and linux 
server.

our situation is that i have set the keylife to one hour for the roadwarrior, 
because when the user of the notebook disconnect his internet-connection 
before he closed the tunnel, the tunnel still be established. now I thought I 
limit the time and so the tunnel breaks after the time of 20 minutes.
BUT the windows roadwarrior wouldn't rekey ( renegotiate ) the connection.
After this time, the tunnel collapses and I get this error message in 
auth.log.
