major problem with ntlm_auth and winbindd pipe

[Habegger Lukas, ERZ-AZD-AIL]

Hi All,

I use freeradius for peap-authentication and I have multiple
samba/winbind
services to authenticate against to different ADs.

In my setup I use a perlscript to start the right winbindd for a
request.

Now I have the problem that the winbind-pipe sometime dies. 

Has anyone experiences with dieing winbind-pipes in a freeradius peap 
environment?

Can anyone help me?
