OK, after investigation (on IRC) it seems that because of a failed post install script run during rudder-agent installation, the /opt/rudder/etc/uuid.hive file contained a placeholder text instead of a good uuid, which has been accepted by Rudder.

Enclosed to this ticket is a script which extracts all the node names in the Rudder LDAP tree, so we can remove the offending one.

The offending node looks like this (LDIF extract):

# \23 The content of this file should be replaced with a valid U, Nodes, Acce
 pted Inventories, Inventories, rudder-configuration
dn: nodeId=\23 The content of this file should be replaced with a valid
U,ou=N
 odes,ou=Accepted Inventories,ou=Inventories,cn=rudder-configuration
nodeId: # The content of this file should be replaced with a valid U

I'm creating a script to fix this, but we will have to find why this happened.

It seems at the first glance that it is due to a multiarch glitch in RHEL 6.

Enclosed to this ticket are two scripts:

One to extract all the nodes in Rudder
One to correct this problem

The script to correct the problem should be run as root on the broken Rudder server, and then the user should click on "Clear Caches" in the Administration -> Policy Server tab.

OK, so there is two bugs here:

- we should not accept node with ID longer than 50 chars
- a "#" in a node id cause the javascript responsible to display node details to fails (and so we can't delete it anymore).

So, I propose to normalize accepted node ID to [a-zA-Z0-9\-]{1,50}, what will resolve the two problems.
(we can't simply check for a valid UUID, because some special nodes have special ids, like "root". And I'm not sur we want to forbid arbitrary names for node IDs)

I'm bumping the UUID creation at the top of the rudder-init script to prevent a broken UUID from beeing used even if cf-agent fails.

It looks like the original reason for this happening may well be dependency problems on the rudder-agent RPM used by Dennis, see #3546.
