[rt-users] Locking a field

[mb at cowville.org]

Hello all!

I'm running RT, v 3.6.0 on RHEL ES v4.

I'm setting up this RT instance to authenticiate users through my  
University's web-based authenticiation system, then give them limited  
access so they can create tickets.

Long story short, my goal is to not allow (unprivleged) users to  
modify the "Requestor" field for a new ticket that they are creating.  
The only way that I could think of was to create and modify a  
/local/html/SelfService/Create.html file, doing something like adding  
DISABLED to the end of the input tag for that field. I realize it's  
theoretically possible for a savvy user to modify the headers (or  
thier browser) and thus thwart this protection, but that risk is one  
that I guess I'd be willing to take - I'm more concerned about it  
getting accidentally changed by a user.

Is there a better way to do this within the interface of RT, or is  
this the best way?

Thanks!
