I've filed this as a bug report with Apple but would be very appreciative if some kind folks could help me to test it.

Basically we've upgraded all our Macs (about 400 in total) to 10.5.8. All seemed fine but our new users are not having their mail auto-configured fully. In WGM for com.apple.mail.managed we set:-

ONCE:-
AuthenticationScheme GSSAPI
FullUserName %@
SMTPHostname server.domain.com

ALWAYS:-
AccountType IMAPAccount
EmailAddresses 0 %@@domain.com
Hostname server.domain.com
Username %@

In 10.5.6 (and before) this worked fine (I'm not sure about 10.5.7). I still have a 10.5.6 laptop and if a new user logs on to this then their mail account is created fine. On a 10.5.8 station, the account is setup but without authentication information or an SMTP server (the "once" preferences).

Looking inside a new user's /Library/Preferences folder after they've logged in to 10.5.8, nothing is written to com.apple.mail.managed except a uniqueID.

A user who has logged in to 10.5.6 has a com.apple.mail.managed that contains:-

AuthenticationScheme
FullUserName
SMTPHostname
uniqueID

Could anybody test this for me please? It only affects users who have not previously had their account auto-configured which is why it's only just shown up (we've just started the new school year with 150 new users).

For information we're a dual AD/OD site.

Thanks in advance.
