[Zope] Giving access to error_log.showEntry to non-Manager users

[martin.gfeller at comit.ch]

Dear all,

I'm trying to give all authenticated users access to the error log of an

error that they just encountered. I'm using the error_log_url available
in
the standard_error_message to direct the user to the appropriate error
log.

This works fine for users with Manager role, but I cannot make it work
for other authenticated users. I modified the error_log access to 
include 'View', 'View management screens'  and 'Log Site Errors', 
but it doesn't help, unless I give 'View management screens' 
to Authenticated in the Zope root, which opens up too much. 

The actual access error is on 'manage_page_header' - I append the error 
traceback. 

I've also tried to access the error_log through a DTML with
proxy set to Manager, to no avail. 

Any tips? 
Thank you and best regards,
