cyradm referall 2.4.1 version

[Lucas Zinato Carraro]

I have 3 Frontends in DMZ,  4 Backends in Intranet
and a Administrative Station in other network.

The administrative station, and clients stations  can not connect
direct to backend  servers.

In imapd.conf i enable the parameter:

proxyd_disable_mailbox_referrals: 1


With 2.3.16  dont have problem to issue commands direct in frontends
using cyradm.

cyradm --user cyrus  frontend2316

info user/mailbox   - OK
lam user/mailbox   - OK
sam user/mailbox  - OK
cm  user/mailbox   - OK

With 2.4.X :

cyradm --user cyrus  frontend241

info user/mailbox   - OK
lam user/mailbox   - OK
sam user/mailbox  - timeout error
cm  user/mailbox   - timeout error

Without firewall ( frontend  -  firewall - backend )   :

info user/mailbox   - OK
lam user/mailbox   - OK
sam user/mailbox  - Ask for backend  password
cm  user/mailbox   - Ask for backend  password

I keep same config between cyrus 2.4.1 and cyrus 2.3.16.

Its possible to disable referall to cyradm ?
