cyrus 2.3.11: cyr_expire can't remove deleted mailboxes

[Ernst Jeschek]

Hello list members,

we have delete_mode and expunge_mode set to delayed on our cyrus
2.3.11 backend. When cyr_expire tries to remove deleted mailboxes, it
fails with the following error:

  cyr_expire[24222]: can not connect to mupdate server for delete of 'DELETED.DELETED.user.<username>.<folder>.47EA470C.47EA773C'
  cyr_expire[24222]: couldn't authenticate to backend server : SASL library not initialized 

We are currently upgrading our murder installation from 2.2 to 2.3.
master already is 2.3.11, the frontends are still 2.2.13 and this is
our first 2.3.11 backend. Upgrading is done by transfering the
mailboxes from the old backends to the new.

We are using cyrus 2.3.11 with sasl2 2.1.22. For authentication
between the servers we are using kerberos V (GSSAPI).

'mupdate -m' works.
