Does anyone understand this problem or have an idea of how to investigate it?

AFAICS the access rights to my authorized_keys file get corrupted. Before I try to login it shows on the remote host: # ls -l /home/hdunkel/.ssh/authorized_keys -rw------- 1 hdunkel users 1406 Jun 15 14:34 authorized_keys When I try to login I am asked for a password (although authorized_keys is set correctly). After this attempt I see on the remote host: # ls -al /home/hdunkel/.ssh/authorized_keys -rw------- 1 4294967294 4294967294 1406 Jun 15 14:34 authorized_keys "sshd -d" shows that sshd doesn't like this. Using the regular Squeeze kernel without vserver patch there is no such problem. /home is mounted via NFS: # cat /proc/mounts | grep /home nfs-home:/space/home /home nfs4 rw,relatime,vers=4,rsize=1048576,wsize=1048576,namlen=255,hard,proto=tcp,port=0,timeo=600,retrans=2,sec=sys,clientaddr=172.19.96.103,minorversion=0,addr=172.19.96.215 0 0 The NFS server runs Squeeze, too.
