Overview
This Plug-in provides the ability to update Appian user profiles from data retrieved from an LDAP server. The data that can be synchronized include all the default user profile fields except the username (e.g. first name, last name, address, phone, supervisor, title, etc…) as well as the custom fields.
Key Features & Functionality
See the instructions documentation (attached PDF) and https://community.appian.com/w/the-appian-playbook/520/ldap-synchronization for more information.
Seems like the plug-in is attempting to use a version of the isValidNameLength method which is no longer available in 22.3
It is deprecated since at least 20.3 so must have been removed.
