The hope is to bypass the signon screen.  Much like you can do with 
iSeries Access.  You can tell iSeries Access to use either the signin you 
used to originally connect to the i5, or to use EIM.

Now, with FTP you can take someone who signs in with anonymous, or with an 
ldap id, and tell the ftp server to use this other i5 id instead.  You can 
configure a many-to-one.  For example, if one customer has 5 ldap id's to 
get to your system (1 for each salesperson for example) then all 5 ldap 
id's can be tied back to one i5 id.  Granted, it makes logging a little 
interesting.  But it gives YOU the option as to what you want to do at 
your shop.

And the odds are high that all 5 of these salespeople would have the same 
menu anyway.  Also the telnet exit program does allow you to specify 
initial program.  I didn't research it enough to see if it allows you to 
pass it a parameter.  Not that you want to create a separate program for 
each ldap user to differentiate menus, but you could.

Re: [Security400] iSeries Telnet authentication






Forgive my ignorance, but what is the point of this?

Whenever I telnet to the AS/400, I want to get to my AS/400 menus under 
my profile.

If you were validating against an external LDAP, would this validation 
be prior to displaying the signon screen thus having 2 realms of 
authentication?
