[rt-users] 3.8.6: WritableAttributes error in Web.pm's AttemptExternalAuth

[Philip Shore]

Hi Keven,

Thanks for the quick response.  That patch does indeed fix the error and 
now I can see the self service interface after authenticating.

Re, our config.  I have attached the complete config in case you would 
like to provide any words of wisdom.

We are using a custom apache single sign on module that puts the users 
id into remote_user then we auto create the user after lookup their 
name, email address etc from an ldap source which I guess is the old 
handler.  I am taking a look at  RT::Authen::ExternalAuth  to see if it  
would be a better solution for us.

Many thanks,
Philip Shore.
