I have setup ldap authentication in file : /opt/splunk/etc/system/local/authentication.conf
And looking at the splunkd.log everything seems fine. I can see the LDAP credentials and users being cached. I have tested to reload splunk using the LDAP credentials from the command line and everything works perfectly fine.
Now, THis does NOT work in the web-ui. I cannot log in there using the ldap credentials.
I have tried: Manager » Access controls » Authentication method --> LDAP (as that was inactive)
then : Configure Splunk to use LDAP and map groups (my strategy was there)
and ENABLE it as it looked disabled.
In the end I have "Reload authentication configuration" , even I have restarted the server but I cannot log into the web-ui using the LDAP credentials.
