Alfresco SOLR - HttpChannel COMMIT for /solr/admin/info/system 403

[milans_cca]

Hello,

I’d like to ask for assistance with solving our problem with Alfresco SOLR.

We’re running Alfresco Community distribution with Alfresco SOLR on Windows Server 2022 with using shared secret between Alfresco and SOLR.

Our versions used are:

• alfresco-content-services-community-distribution - 25.2.0
• alfresco-search-services - 2.0.16
• OpenJDK 21 - OpenJDK21U-jdk_windows_hotspot_21.0.8_9

We’ve configured this configuration for Alfresco and Solr:

Alfresco

F:\opt\eud\dms\tomcat\shared\classes\alfresco-global.properties

# SOLR

index.subsystem.name=solr6

solr.secureComms=secret

solr.sharedSecret=secret

solr.host=127.0.0.1

solr.port=8983

SOLR

F:\opt\eud\dms\alfresco-search-services\solrhome\alfresco\conf\solrcore.properties

F:\opt\eud\dms\alfresco-search-services\solrhome\archive\conf\solrcore.properties

F:\opt\eud\dms\alfresco-search-services\solrhome\templates\rerank\conf\solrcore.properties

F:\opt\eud\dms\alfresco-search-services\solrhome\templates\noRerank\conf\solrcore.propertiesF:\opt\eud\dms\alfresco-search-services\solrhome\conf\shared.properties

# none, https

alfresco.secureComms=secret

alfresco.secureComms.secret=secret

F:\opt\eud\dms\alfresco-search-services\solr.in.cmd

set SOLR_OPTS=%SOLR_OPTS% -Dsolr.jetty.request.header.size=1000000 -Dsolr.jetty.threads.stop.timeout=300000 -Ddisable.configEdit=true -XX:+IgnoreUnrecognizedVMOptions -Dalfresco.secureComms=secret -Dalfresco.secureComms.secret=secret

I also attach part of SOLR log.

Thanks for your help,

Milan
