Domino IMAP/SMTP users cannot authenticate using the Directory Assistance configuration using LDAP to the Central Cloud Directory(for example IBM).
Business and security requirement is that all users need to use only one set of credentials to authenticate to all Cloud services (SSO).
Users are authenticating against a shared Central Cloud Directory. It worked for HTTP without adding any attribute but does not work for IMAP/SMTP.
Looking forward to using SSO for IMAP/POP3 clients without adding any attribute like mailfile, homemail server to LDAP.
