PM94143: USE OF SAFRUNAS RESULTS IN ICH408I MESSAGES TO BE ISSUED AGAINST THE HTTP SERVER USERID

Fixes are available

APAR status

Closed as program error.

Error description

Customer is attempting to use SAFRunAs to force requests to be
issued under a different UserId. But all attempts have resulted
in ICH408I errors issued against the HTTP Server UserId rather
than the SAFRunAs UserId.

Problem summary

****************************************************************
* USERS AFFECTED:  IBM HTTP Server users of the optional       *
*                  mod_authnz_saf on z/OS server               *
****************************************************************
* PROBLEM DESCRIPTION: Configuring with SAFRunAs to run        *
*                      under the client UserID does not        *
*                      work if the server UserID does not      *
*                      also have authority to the file.        *
****************************************************************
* RECOMMENDATION:                                              *
****************************************************************
The switch to the SAFRunAs UserID was not happening early
enough in the processing and the request would fail if the
server UserID did not have authority to the file as well.

Problem conclusion

SAFRunAs has been enhanced to allow switching to the
configured UserID in an earlier phase of processing, to allow
IBM HTTP Server to serve files it cannot itself read.

New Syntax, valid only in global and <virtualHost> context:

Example 1, change the threads identity to the SSL client
authentication provided identity for URLs under /prefix:

SAFRunAs %%CERTIF%% /prefix

Example 2, change early to users home directory (assumes
mod_userdir is configured)

SAFRunAs %%CERTIF%% / &#239; &#244;

Example 3, change the threads identity to a specific surrogate
userid for URL's under /prefix:
SAFRunAs surrogate-username  /prefix

Notes:  No other values are permitted as the second argument.
The server will not switch identities twice during a request
if SAFRunAS is also configured using the one-argument version
inside of <Location> or <Directory> context.
This feature can be used in conjunction with
"AuthBasicProvider saf".

This fix is targeted for IBM HTTP Server fix packs:
 - 7.0.0.31
 - 8.0.0.8
 - 8.5.5.2

Temporary fix
