2.5.10 autocreate on login not working?

[Nels Lindquist]

I'm experimenting with a build of 2.5.10 on CentOS 7 in preparation for 
upgrading from our installed 2.3.16 (built from Simon Mattar's RPMs).

We rely on mailbox auto-creation functionality tied to LDAP 
authentication with virtual domain support; as long as the LDAP account 
exists the mailbox may be autocreated.

As the autocreate patch has now been incorporated in 2.5, I was hoping 
it would work fairly seamlessly, but even after updating all the 
deprecated imapd.conf directives, I'm having trouble.

I'm able to log in to IMAP successfully with an existing LDAP account, 
but a LIST command produces no output, and if I log in with cyradm the 
expected mailboxes are not present.  I'm able to create mailboxes 
manually with cyradm and everything works as expected, but I really need 
autocreate to work.

Here's the relevant section of my imapd.conf:

virtdomains: yes
defaultdomain: example.com
username_tolower: yes
lmtp_downcase_rcpt: yes
autocreate_quota: 0
autocreate_quota_messages: 0
autocreate_inbox_folders: Drafts|Sent|Trash
autocreate_subscribe_folders: Drafts|Sent|Trash
autocreate_post: yes

Anything I've done obviously wrong?
