Openldap2.4 performance boosting

According to my experience, the single directive you should add to db section to improve performance is:

olcDbCacheSize

OpenLDAP tuning guide covers that in section: 21.4.2.

To enable a 200000 entries cachesize use this ldif:

The enumeration of the whole directory (150000 entries) took 15 seconds without cachesize and less than 6 seconds with it.

Instant logger replacement to logback in activemq.5.6.0

In activemq-5.6.0 changing logger to logback is just a matter of seconds:

• Copy the following jar in ${activemq.base}/lib:

  logback-access-1.0.0.jar
  logback-classic-1.0.0.jar
  

• Create a logback.xml file in ${activemq.base}/conf, for example:

That's all.

What about the activemq logback logging to a jms system which is activemq?

Ppolicy overlay password checking module

How about having openldap-2.4 checking whether the changed password is digit-only or alpha-only and than rejecting it?

It could be done with the non-standard password checking module openldap extension, which requires to create a C file with your rules, compile as a shared object and put in a well-known location.

I wrote a step-by-step recipe with a template C file at:
