Using openldap v2.4.50 and noticed that there were some updates which were part of the 2.4.50 release. 

I installed openldap but cannot find those new attributes (pwdMaxLength, pwdStartTime, etc)

> grep pwdMaxL /etc/openldap/schema/*

> grep pwdStar /etc/openldap/schema/*

Maybe I am missing something. 
Could someone please point me in the right direction?

Thank you,

Dave
