I’m running XWiki 16.10.5 with standard flavor as a docker container in an offline environment without internet connection.
I’m trying to install the XWiki extension LDAP Authenicator 9.15.7. I built an XIP package using this pom.xml:
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">

and mvn clean package.
I installed the resulting xpi by unzipping it to /usr/local/xwiki/data/extension/repository/ and installed it using the Extensions Manager. So far so good.
The extension has a few dependencies:
org.xwiki.platform:xwiki-platform-oldcore 8.4
com.novell.ldap:jldap 2009-10-07
org.xwiki.contrib:authservice-backport-api 1.1.1
JLDAP installed fine, but the others have not been installed since they are already installed in general, with a different version (16.10.5), however. And this version mismatch seem to cause problems:
In a testing environment WITH internet connection this mismatch is resolved fine: the depending extensions are linked with “Version 16.10.5 is provided” mentioned. In my offline environment they are not linked, however. According to the logs, XWiki seems to try to locate the old versions online such as https://extensions.xwiki.org/xwiki/rest/repository/extensions/org.xwiki.platform%3Axwiki-platform-oldcore/versions/8.4. As a result LDAP authentication fails with a ClassNotFoundException: org.xwiki.contrib.ldap.XWikiLDAPAuthServiceImpl and consequently: Failed to get the configured AuthService, fallbacking on standard authenticator.
How to tell my offline XWiki to use the 16.10.5 version instead and make the LDAP Authenticator extension work in my offline environment?
This means that the extension org.xwiki.contrib.ldap:ldap-authenticator (in which this class is located) is either not installed (but you indicated that it installed fine), or not loaded after a restart. If it’s the latter, you should see a warning in the startup log explaining why this extension is invalid (and so, not loaded).

The Extension Manager insists that the extension is installed, however - disregarding the mentioned issues with the dependency versions.
Are you sure you looked at the startup log, what you get right after XWiki is restarted, before even accessing it ? What you pasted above is printed when XWiki tries to use the configured authenticator.
If you never restarted after the install, then maybe you should try it. It’s possible something caused a classloader problem after the install.
I don’t really understand which issues you are referring to. As you mentioned, the extension installed fine.
No, I don’t think those are linked in any way. What tried to access https://extensions.xwiki.org/xwiki/rest/repository/extensions/org.xwiki.platform%3Axwiki-platform-oldcore/versions/8.4 is most probably the UI which list the dependencies, to gather more information about this dependency. If the dependency was a problem, it would have never installed the extension in the first place. And at runtime there is no reason for this extension to check the dependencies in any way.
good to know. So the issue is probably something completely different.
I did restart XWiki, however (podman compose restart). Here’s the full startup log:

The jar file in my xip package does not contain any class files. Something went wrong when creating the package I guess. The jar contains nothing but meta information:
Solved: My local Maven repo in ~/.m2/repository seems to have been damaged. I removed it (rm -r ~/.m2/repository) and rebuilt the package (mvn clean package) and the JAR file looks fine again.
