I’d encourage you to post what you’ve configured in your conf/sonar.properties file, as well as more complete logs surrounding the error you’re receiving.
I was able to figure out the issue, it was getting ‘Null’ value from Group mapping function which is kind of weird , the same search is working fine in LDAP Browser. after i removed the LDAP Request tag, it is working.
(&(objectclass=Group)(cn=GBL-Harmony-*)).
Is there any reason the filter which is working in LDAP browser is not working in SonarQube?
