We are about to seed our new instance of Jive Express with core users.
Our (strange) organization uses a format like jbd123 in LDAP (UNIX) for uid. So John B. Doe has the email address firstname.lastname@example.org.
John also has an Exchange account where he can choose his own email address - say he picks email@example.com (but his UID in AD is jbd123). He uses this account 99.9% of the time. He might not forward or even ever check his firstname.lastname@example.org mailbox.
Is there a best practice for what to use for username/email address if we expect to move to SBS in the future? I would think that we would be authenticating against LDAP; is there any reason to use email@example.com over firstname.lastname@example.org or vice versa?
