Description Jan Pazdziora 2013-06-04 14:53:58 UTC
+++ This bug was initially created as a clone of Bug #970547 +++

Description of problem:

When you have a web service using normal basic authentication, your logins will look like "alice" and "bob". When you then enable mod_auth_kerb on that httpd server, the logged in user will be "alice@REALM.COM" and "bob@REALM.COM". Which are completely different users in that web application's database so after using SPNEGO, people will not see their data.

It is necessary to use a

   KrbLocalUserMapping On

directive which is undocumented anywhere in the mod_auth_kerb documentation beyond on line in the Changes file in the mod_auth_kerb-5.4.tar.gz:

   *implemented KrbLocalUserMapping i.e. to strip @REALM from username for further use

Version-Release number of selected component (if applicable):


How reproducible:


Steps to Reproduce:
1. Enable mod_auth_kerb and try the user names not to have the @REALM so that it matches the basic authentication.
2. Try to find the documentation.

Actual results:

You will only find KrbLocalUserMapping (which is what you want) on Stack Overflow.

Expected results:

The directive will also be in /usr/share/doc/mod_auth_kerb-5.4/README.

Additional info:

Basically, please amend the README shipped with the module. Of course, getting it to upstream as well (not just Fedora but module's upstream) would be the best.
