Hi, we just started a topic at the horde wiki about CAS. Anyone interested in using CAS for horde/imp can read and improve it at will. http://wiki.horde.org/CASAuthHowTo Note that it doesn't contain information for all Horde components yet (eg: we'd like to see Gollem -ftp- using CAS too; we have some initial code for that but it's been put at a lower priority temporarily). -- Velpi
