I am trying to debug an apache to ldap connection. The Apache server just reply with an Error 500 in the access.log file. I do not have any error in the error.log file.
I have seen that the LDAPLibraryDebug Directive is only available in Apache 2.4 and I am using Apache 2.2. Any ideas on how add more debug messages in the error log?
You can add "LDAPLibraryDebug" to a 2.2 server with this debug module:
https://github.com/covener/apache-modules/tree/master/mod_ldap_debug
To debug mod_ldap (and mod_authz_ldap) you need to have both services (Apache and LDAP) in debug mode. For Apache use configuration parameter in sequence :
LogLevel debug
More info available on follow URL https://www.loggly.com/ultimate-guide/apache-logging-basics/
For LDAP service (if you use OpenLdap) stop standard service and start OpenLdap in foreground debug mode with (example):
slapd -d 128
