After upgrading to 8.3, one functionality that broke for me was my LDAP script that enable users to search for users and share resources with them (trends, messages, etc). This post helped shape my 8.1 code. The new LDAPHelper requirements are documented in the 8.3 javadoc - which now requires adding a context to to the LDAPHelper, the password needs to be a SecreteConfig type, and you need to define getReturnedAttributes function.
I have my 8.1 LDAP script updated to with with 8.3 using a plain text password but ideally this code could be modified to work with the secrets provider. Currently Im getting a type incompatibility between what the secrets library provides; com.inductiveautomation.ignition.common.secrets.PyPlaintext and what LDAPHelper needs: com.inductiveautomation.ignition.gateway.secrets.Plaintext. Any help here would be appreciated
