NFS and rpcbind issue

[vincent-kali]

Hi,
I'm facing an issue when trying to enable NFS on Alfresco 5.0d, running on Debian 7.
It seems that JAVA is not allowed to register RPC service on local rpcbind service.
I'm using the following config:

nfs.enabled=true
nfs.user.mappings=admin,user1
nfs.user.mappings.value.admin.uid=0
nfs.user.mappings.value.admin.gid=0
nfs.nodeMonitor.enabled=${nfs.enabled}
nfs.mountServerPort=2050
nfs.nfsServerPort=2049
nfs.rpcRegisterPort=0
nfs.portMapperPort=111
nfs.portMapperEnabled=false
nfs.sessionDebug=
nfs.mountServerDebug=true
‍‍‍‍‍‍‍‍‍‍‍‍‍‍

Here's the log:

Did somebody face similar issue ? Any advice ?
Thanks,

What happens if you specify a non zero value for nfs.rpcRegisterPort=0

Who are you running as?  In particular are you allowed to bind to privileged ports?

I tried to specify a high port (nfs.rpcRegisterPort=50001) but error remains.
Alfresco is started as root (I think this is required, isn't it ? )

Should I dig into JAVA config? any other idea ?

Thanks,
Vincent
