     1= AUTHSERV GATEWAY SCRIPTS = 
     2    Original author:  Beth Mercer - 20081031               
     3 
     4== Overview == 
     5The AUTHSERV interface originated with the EDIR web gateway but was separated from the  
     6EDIR interface in July of 2005.  Because it started out as part of EDIR, the Perl 
     7modules that are utilized by the AUTHSERV interface contain many functions that are 
     8simply not pertinent to the AUTHSERV interface.  Someday they may be dropped. 
     9 
     10== Configuration Files == 
     11 
     12Configuration files are located for every instance under $HOME/AUTHSERV<''INST''>/config 
     13 
     14=== admin_actions.cfg === 
     15This file contains data from which Admin Actions pick list is built.  The  
     16file can be copied to all servers hosting the same AUTHSERV instance. 
     17 
     18=== registered_clients.cfg === 
     19This file contains data used by authentication service to determine if authentication is performed and.  If authentication was performed it then determines what information is provided as a result of authentication and confirmation of authentication.  The file can be copied to all servers hosting the same AUTHSERV instance 
     20=== runtime_common.cfg === 
     21This file contains a subset of runtime configuration elements that are constant between servers hosting gateway - see runtime.cfg.  The file can be copied to all servers hosting the same AUTHSERV instance. 
     22=== runtime.cfg === 
     23This file contains runtime configuration data used by AUTHSERV CGI scripts
