Ensure you use the following best practices during LDAP configuration for Avaya Aura® Device Services.
Map SMGRLoginName to the email address or User Principal Name (UPN) attribute. You can update the mapping on the Attribute Mapping page in the Avaya Aura® Device Services web administration portal.
Turn on LDAP synchronization between System Manager and LDAP.
Even if the above best practices are not followed, make sure you include a Microsoft Exchange Server (SMTP) handle in System Manager for all user records. This facilitates correlation of System Manager user records with LDAP records.
These best practices are not applicable for Avaya Aura® Device Services deployments in an environment without Avaya Aura® because Avaya Aura® Device Services does not interact with System Manager in this environment type.
