How To Fix SLDAP_ICM017 - Target for referral "&1&2&3&4" not maintained

SAP Error Message - Details

• Message type: E = Error

• Message class: SLDAP_ICM - ICM LDAP Plugin: Messages

• Message number: 017

• Message text: Target for referral "&1&2&3&4" not maintained

What causes this issue?

The directory service has sent a referral or search result reference,
and the ICM LDAP plug-in is configured to chase this object.
The option that referrals and search result references can be chased
without having a whitelist entry in the own system has not been set.
Therefore, the ICM LDAP plug-in searches the LDAP Server customizing for
an entry of LDAP application "Referral Target (Whitelist)" matching the
provided hostname and port.
No such entry could be found; therefore, referral chasing has been
terminated with this error message.

System Response

The system issues an error message and will not allow you to continue with this transaction until the error is resolved.

How to fix this error?

Either maintain the referral target in the whitelist or enable trust to
all referrals received from the directory service in the LDAP server
customizing of the server which sent the referral.
