Thanks. This is consistent. But i still got error...
Though you showed me the right way to fix it.
The problem was coming from selinux.

My amanda server is running with CentOS 5 with
selinux installed by default.
making selinux permissive fix my problem :

setenforce 0

This default installation incompatibily (i installed amanda with an rpm
for rhel5) worth to be more know for redhat, fedora users.
