Alan, Arran, What's the policy on adding vendor-specific attributes to vendor dictionaries for attributes that will never be sent over the wire, i.e. 'temporary' attributes for policies that will eventually be distributed? I currently have an attribute that I would like to add to 'our' (i.e. Janet's) dictionary that is just a processing flag. The reason I don't want to use one of the Tmp-* attributes is because they may be in use by other policies in the deployer's policies, so a specific attribute for this would suffice. If you "don't care", then great, but suggestions/recommendations are welcome :-) Thanks :-) Stefan Paetow Moonshot Industry & Research Liaison Coordinator t: +44 (0)1235 822 125 gpg: 0x3FCE5142 xmpp: stefanp@jabber.dev.ja.net skype: stefan.paetow.janet Janet, the UK’s research and education network.
