replicated to Server1.
The replication Server2->Server1 is done with kerberos authentication.
Server1 receives the replication session, successfully identify the
replication manager, start to receives replication extop but suddenly
closes the connection.

[19/Nov/2014:14:21:39 +0100] conn=2980 op=-1 fd=78 closed - I/O
function error.
The reason of this closure is logged in server1 error log. sasl_decode fails
to decode a received PDU.
[19/Nov/2014:14:21:39 +0100] - sasl_io_recv failed to decode packet
for connection 2980
I do not know why it fails but I wonder if the received PDU is not larger
than the maximum configured value. The attribute nsslapd-maxsasliosize is set
to 2Mb by default. Would it be possible to increase its value (5Mb) to see if
it has an impact
[...]
I set nsslapd-maxsasliosize to 6164480 on both machines, but the problem
remains.
