Update the User Email Attribute from LDAP
When Presto is configured to use your LDAP Directory as the User Repository, Presto is configured by default to expect user email addresses in the mail attribute for LDAP user entries. If your LDAP Directory uses a different user attribute to store email addresses, you must update LDAP configuration information in Presto to ensure that email notifications are successfully delivered.
To update the mail attribute
1. Click 
Admin Console in the Presto Hub main menu. 2. Expand the Presto Repositories section and click User Repository - LDAP.
3. Click Advanced Options and scroll down to find Presto Query Properties.
4. Change the User Email address property to the name of the LDAP user attribute that contains user email addresses.
5. You may also want to update the list of attributes in Export User Attributes as Presto Attributes and Attributes Used in Wildcard Search fields as these properties commonly include the mail attribute.
6. Click Save the changes.
7. Restart the Presto Server to apply these updates.
