How To Fix SLDAP_ICM012 - SSL client identity &1 (with PSE file name "&2") cannot be used

SAP Error Message - Details

• Message type: E = Error

• Message class: SLDAP_ICM - ICM LDAP Plugin: Messages

• Message number: 012

• Message text: SSL client identity &1 (with PSE file name "&2") cannot be used

What causes this issue?

The provided SSL client identity &V1& cannot be used to establish a
secure connection.
This check verifies:
For the SSL client identity &V1&, a PSE file name "&V2&" can be created
(when the former content was empty, this step failed).
For the PSE file name "&V2&", exactly one entry can be found in the
database table of PSE file headers (SSF_PSE_H).
For an SSL client identity regularly maintained in transaction STRUST,
those checks should pass.

System Response

The creation of the ICM LDAP plug-in-based connection was canceled.
