How To Fix SLDAP_ICM004 - Request to directory service "&1" results in error &2&3&4

SAP Error Message - Details

• Message type: E = Error

• Message class: SLDAP_ICM - ICM LDAP Plugin: Messages

• Message number: 004

• Message text: Request to directory service "&1" results in error &2&3&4

What causes this issue?

This message is issued when a request to the directory service via the
LDAP protocol could not be sent (a negative number in front of the
textual message might be an indicator for an error location in the LDAP
client library) or was sent to the directory server which in turn
responded with an error message (positive number).
This error is typically the result of semantically/structurally
incorrect data, for example:
Authentication with incorrect username or password.
Change operation without enough authorization in the directory server.
Change operation which violates rules in the directory server (for
example attribute constraints for object classes).
If the returned error code is 10 ("Referral"), you can configure the ICM
LDAP plug-in to perform referral chasing. See the documentation of the
configuration option "Referrals" in the LDAP Server customizing.

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?

The textual error message which is part of this message (eventually
clipped) is generated by the LDAP client library and therefore not part
of the translation process.
When the information provided by this message is not enough to resolve
the issue and the error indicates it has been generated on the directory
server, contact the directory service administrator for assistance.
