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 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): mod_auth_kerb-5.4-9.el6.x86_64 How reproducible: Deterministic. 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.
