Hab hier mal nen Auszug aus dem Workaround. Das mit den PTFs ist schon zu hoch für mich, vielleicht versteht das ja jemand und kann mir nicht AS400 Crack erklären was gemeint ist:

Document Title
Message 404 Forbidden By Rule from Web Admin GUI for LDAP

Document Description
After setting up the Web Admin tool for IBM® Directory Server, users Select the IBM Directory Server from the iSeries Task Page and get a 404 Forbidden by Rule message.

This is caused by a code level mismatch between IBM® WebSphere® Express 5.0 (SF99272) and HTTP (SF99099). Order the latest WebSphere group PTF: SF99272 (you will also receive HTTP PTF SF99099 and JAVA PTF SF99269).

A potential workaround is to use the 5722IWE SYSINST Plug-In Quick Fix Trick:

Note: This is not guaranteed to work. If you get an MCH4437 Escape Message, you must put on the PTFs. This workaround should be used only if you are in dire need of access now. 1 Save the original copy of /QIBM/UserData/webase/ase5/sysinst/config/cells/plugin-cfg.xml. 2 Edit /QIBM/UserData/webase/ase5/sysinst/config/cells/plugin-cfg.xml and add the line <VirtualHost Name="*:0"/> as follows:

<VirtualHostGroup Name="default_host">
<VitualHost Name="*:0"/>
<VirtualHost Name="*:2010"/>
<VirtualHost Name="*:2001"/>
</VirtualHostGroup>
3 Save the file.
 4 Wait 60 seconds for this new plug-in file to be picked up by the Apache plug-in.
 5 Try the Web page access again. If it does not work, you will need the PTFs.
