Hello all,
we are using SonarQube Developer Edition 10.2.1 on a Debian 11 System.
For security reasons our LDAP team wants to urge us to change connection from LDAP to LDAPs.
This also affects our sonarQube instance.
Our LDAP/LDAPs Server is unfortunately running under windows 
However while a plain LDAP connection is working as a charm, LDAPs does not. Yet even sonarQube fails to start completely when using LDAPs.
Our Config for LDAPs in the sonarproperties is:
# Enable usage of StartTLS (default : false)
ldap.StartTLS=false
#--------------------------------------------------------------------------------------------------
# LDAP CONFIGURATION
sonar.security.realm=LDAP
ldap.url=ldaps://ldapsServer
ldap.bindDn="CN=Admin,OU=subgroup,OU=group,DC=here,DC=local"
ldap.bindPassword=sectet password
ldap.authentication=simple
sonar.security.localUsers=admin
# User Configuration
ldap.user.baseDn=OU=subgroup,OU=group,DC=here,DC=local
ldap.user.request=(&(objectClass=user)(sAMAccountName={login}))
ldap.user.realNameAttribute=cn
Using this config, Sonar is starting but after a few seconds it crashes completely. The sonar.log does not tell us anything but the weblog says:

Can please anyone tell us what is going wrong here?
