Distech Controls ECLYPSE ECY-STAT User Manual page 59

Should the connection to the RADIUS server be temporarily lost, ECLYPSE controllers have a fall
back authentication mode: Users that have already authenticated themselves with the RADIUS server
and then the connection to the RADIUS server is lost, these users will still be able to login to the con-
troller as their successfully authenticated credentials are locally cached.
The user profile cache is updated when the user authenticates themselves while there is a working RADIUS server
connection. For this reason, at a minimum, admin users should log in to each ECLYPSE controller at least once, so
their login can be cached on that controller. Otherwise, if there is a RADIUS server connectivity issue, and a user
who has never connected to the ECLYPSE controller before will be locked out from the controller. It is particularly
important for admin user credentials to be cached on each controller as an admin user can change the controller's
network connection parameters that may be at cause for the loss of connectivity to the RADIUS server.
The port values of 1812 for authentication and 1813 for accounting are RADIUS standard port num-
bers. However, other port numbers may be used. No matter which port numbers are used, make sure
that the port numbers are unused by other services on this controller and that both the RADIUS server
and the RADIUS clients use the same port number values.
