Red Hat Bugzilla – Bug 970678
Document the KrbLocalUserMapping option in README
Last modified: 2016-04-18 06:25:20 EDT
+++ 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
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):
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.
You will only find KrbLocalUserMapping (which is what you want) on Stack Overflow.
The directive will also be in /usr/share/doc/mod_auth_kerb-5.4/README.
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.
