Symptoms

In a multi-master environment the same CSN is replicated twice as reported in the DS access logs, why?

[31/Jul/2013:02:48:22 -0400] conn=xx op=0 msgId=716 - MOD dn="cn=<CN>,ou=people,dc=<SUFFIX_DN>"
[31/Jul/2013:02:48:22 -0400] conn=xx op=0 msgId=716 - RESULT err=0 tag=103 nentries=0 etime=0 csn=<CSN_1>

[31/Jul/2013:02:48:22 -0400] conn=xx op=0 msgId=721 - MOD dn="cn=<CN>,ou=people,dc=<SUFFIX_DN>"
[31/Jul/2013:02:48:22 -0400] conn=xx op=0 msgId=721 - RESULT err=0 tag=103 nentries=0 etime=0 csn=<CSN_1>


Reviewing the state data shows the csn is for pwdFailureTime

This is also confirmed by reviewing the audit log.
