Please let ejabberd/2.1.10-4+deb7u1 enter Wheezy.
The proposed version is built upon 2.1.10-5 [1] which was
prepared for the first Wheezy point release but missed it by a narrow
margin.
Additionally two more bugs were fixed:
* Disabled SSLv2 and weak cyphers in TLS driver [2].
* Fixed rendering of angle brackets in logs produced for
multi-user chat (MUC) rooms when a plain-text format is enabled for
them (resulting in nicknames disappearing from these logs and similar
issues) [3].
I have verified both of these bugfixes work as intended.
Please see the attached debdiff. It's a bit large but please notice
that half of it is the unborn 2.1.10-5.

+7. Using SCRAM-SHA-1 authentication mechanism
+=============================================
+
+Since version 2.1.9 ejabberd supports the SCRAM-SHA-1 authentication
+mechanism (which, among other things, allows to not store passwords of
+XMPP accounts in clear text if the internal database backend is used
+for storage). This authentication process implemented by this
+mechanism includes the client sending a so-called "digest URI" which
+includes the server's identity as perceived by the connecting client.
+The SCRAM-SHA-1 RFC document requires this identity to be the
+fully-qualified host name of the server. This hostname is typically
+obtained by the client by looking up a server-specific DNS record of
+type SRV for the XMPP domain the client wants to register in.
+
+Unfortunately, the current implementation of SCRAM-SHA-1 in ejabberd
+is not able to perform the same kind of DNS query as used by the
+clients to know its "canonical" fully-qualified host name.
+Consequently, if the actual hostname of the server differs from the
+name of the XMPP domain it serves, a special option should be included
+in the configuration file to let the server know its hostname as seen
+by its clients. This configuration option is called "fqdn" and it
+expects a single argument -- the fully-qualified hostname of the
+server, as recorded in the appropriate DNS SRV record for the server.
+An example of its usage:
+
+{fqdn, "foo.example.com"}.
+
+It worth repeating that if the server's hostname is not different from
+the name of XMPP domain it servers (for instance, the XMPP domain is
+"example.com" and the server's hostname is also "example.com") the
+usage of this configuration option is not necessary as ejabberd will
+just use the domain name in the indicated case.
+
+It should be noted that while certain clients faithfully implement the
+SCRAM-SHA-1 specification, some other clients diverge and use the XMPP
+domain instead of the fully-qualified hostname of the server in the
+digest URI strings they send. Ejabberd implements relaxed rules for
+interpreting digest URIs to be interoperable with broken client
+implementations.
