How to create a password policy to block the CN as password. This feature is not implemented in the current Password Management version. Is there any way to implement that password policy.
This is neither a feature of eDir nor IDM, but is a feature of NMAS. On eDir 8.7.3.x you should be able to apply SS 206 and get access to this feature. You'll also need the latest plugins which can be installed via auto-update in iManager 2.7. The current IDM plugins (which also include the Password Management plugins) for iManager 2.7 are backward-compatible with IDM 3.0.1. The feature is explained here https://www.novell.com/documentation/password_management33/pwm_administration/data/an4bun5.html
