The NTLM one (in services/ntlm-auth) might be a better example as it is
packaged standalone, while the ldap one is included in the repository
codebase itself (not sure why).

I hope someone else can help you out, but here are some quick hints.

You need to add your new component to the
repository/servers/src/conf/block.xml

next to where the current ldap and ntlm includes are. This block.xml is
the main (or root) block.xml, which either needs to list components
explicitely or have include-instructions to include other
jars-with-block.xml.

The include instruction should be something like ibm:jarname, in which
"ibm" corresponds to the subdirectory in your repo:

\repository\server\DAISY_MERLIN_REPO\ibm\jars

Also about this line:

<resource id="ibm:ibm_bluepages_authentication" version="1.0"/>

I don't know what the ibm_bluepages_authentication.jar is, but just to
be sure: it should not be the jar that you are creating, since you don't
need to add that one to the classpath.
