admins access from Cyrus 2.4 proxy

[David Mayo <D.J.Mayo@xxxxxxxxxx>]

We have started the process of upgrading our Cyrus IMAP service from 2.3 
to 2.4. We upgraded the proxy IMAP server earlier this week and 
subsequently noticed that quotas can no longer be viewed or set from the 
proxy IMAP server.

Cyrus 2.3 front end behaviour:

== cyradm ==

proxy> lq user.test
  STORAGE 121/250000 (0.0484%)
proxy>

== Proxy ==

C: 5 GETQUOTA user.test
S: 5 NO [REFERRAL imap://;AUTH=*@backend.bath.ac.uk/user.test] Remote 
mailbox.

== Backend ==

C: 5 GETQUOTA user.test
S: * QUOTA user.test (STORAGE 121 250000)


Cyrus 2.4 front end behaviour:

== cyradm ==

proxy> lq user.test

proxy>

== Proxy ==

C: 4 GETQUOTA user.test
S: 4 NO Permission denied

== Backend ==

C: 4 Getquota {11+}
user.test
S: 4 NO Permission denied


Direct to Cyrus 2.3 backend using the same admin user:

== cyradm ==

backend> getacl user.test
  STORAGE 121/250000 (0.0484%)
backend>

== Backend ==

C: 1 Getquota {11+}
user.test
S: * QUOTA user.test (STORAGE 121 250000)
1 OK Completed

Server details: 2x Solaris 10 x86 machines, proxy server 2.4.16, backend 
server 2.3.13.

proxyd_disable_mailbox_referrals is set to true on imapd.conf on the 
proxy server for both versions.

It's good to see that an IMAP referral isn't being generated by the 
front end server - we use Kerberos authentication so the login was 
happening automatically anyway - but is it expected behaviour that the 
admin user be denied admin rights when logging in from a proxy server? 
Or should I raise a bug about this?

Thanks,


Dave.
