There's been various one-time password features in the works for OpenLDAP -- the popular open-source implementation of the Lightweight Directory Access Protocol -- in various code-bases while now within their mainline Git tree they have time-based one-time password (TOTP) support.

A Phoronix reader pointed out this week that OpenLDAP has mainlined their Time-based One-Time Password support.

For LDAP users wishing to find out about this new feature can find the build details via this commit from 2 July adding in the support.
