Just to let you now. My errors where based on a wrong kerberos
implementation. I had the heimdal implementation installed.
"apt-get install krb5-user" fixed my issues.

Best regards,

> I have a setup containing an old windows 2003 ad server which i am planning to replace with 2 samba 4 dc's. Replication between these 3 servers is working fine. Sometimes i am not able to login to windows workstations and bind shares with net. Due to the fact that everything is going back to normal once i stop the samba service on the 2 samba 4 machines it looks like these machines do not answer authentication requests correctly. Do you have any pointer where i should look into? Try to find anythins in the logs but haven't found anything yet. Also google was not that helpful.
> The only thing i have till now is that the net command throws "system error 86" -> network password is wrong (translated from german, so the english error message might look slighly diffrent). Windows logon only state username and or password is wrong.
> Samba version is 4.2.9 Sernet
> Debian Wheezy
