Our security group is hassling us because we don't currently provide them an audit log of failed login attempts on our LDAP servers. For most of our other systems, we simply provide them a syslog feed with this information. However, openldap doesn't appear to have a logging level that provides detail about login attempts on a single line, but rather across many lines that would need to be correlated. It seems more like connection debugging logging as opposed to authentication logging.
It looks like we might need to set up an accesslog overlay to log all of the attempted binds and then have a separate process that runs through that and generates the syslog feed to our ISO group's central logging server? That's a bit more overhead than I would like.
Are there any other simpler ways of generating failed login logs?
Thanks much.
