You can use the information and link provided here to detect
and handle modrdn operation.
Some changelog connectors (the
IDS Changelog Connector and
Sun
Directory Change Detection Connector) can detect
modrdn operations
as the underlying LDAP servers' changelogs provide it. When this happens
the Changelog Connector tags the Entry with the
modify operation.
The changelog attributes contain the "newrdn" attribute when the operation
is modrdn. The LDAP Connector detects in its modEntry method if the
"newrdn" attribute exists and if so, it replaces the rdn in the target
$dn with the new value and does a context rename operation.
Note: LDAP
configurations in Delta mode before IBM Security Directory Integrator v7.0
have treated modrdn operation as generic and have not handled it at
all. Now they will handle it as modify.
Also, such configurations will rename $dn if the "newrdn" attribute
is provided.
