Any new TCP socket connection would require a login so that it's access level could be checked so any client should always be validated.    If the last remaining socket at any given logon level disconnected then the associated UCM would logout also.

Having two UCM's would allow them to be pooled still so any number of users with two different passwords would always be connected, some using one UCM and some the other.     My original PS comment would allow multiple levels to be achieved using a single UCM.

If the EM500 capabilities might allow such an arrangement to be coded in firmware it sounds very sensible and I don't think it causes any security problems.

Just something to think about.... You need to be able to decode the passwords in the CCLX file to be able to restrict/grant certain levels of access. The encryption method is not available to the public.

I don't really need to know the passwords though....    The first connection I would know the password that was used to logon to the UCM (and I would remember it) and subsequent TCP connections I would check passwords and they would have to be the same or I would enlist another UCM.   If there is any useable standardised form of TCP socket security/encryption available I could offer the same.

For my 'PS' approach ... I dont actually need to know the passwords but I do need to know the level of the access that was granted , and hence my question as to whether the UCM can advise me of this (?).  This is so I could ensure that passwords that have lesser levels can't send commands above their level.  I would logon to the UCM at the highest level of the connected clients.  This would require a few logon tests to validate each password and also to establish which was the highest level.

Alternatively I could create a set of my own passwords just for users (eg iPhone clients) that went via my proxy device.   They might be the same as the Comfort passwords but they could be different and mapped by some configuration (web page/telnet) to a suitable Comfort UCM password.

It would be much better if this was a Cytech implemented feature within the Ethernet UCM of course.

When a user logs in sucessfully, the UCM will reply LUnn where nn is the user number. You should be able to use this to map a code with a user

To know the authorisations of each user, you would need to have access to the cclx file for Security > User codes

So, to clarify, is this new hardware, or something that can be intefrated in to the ethernet modules ?
