LDAP configuration resisting deletion while causing repeated warnings

At one time, on a deployment I administrate, I had tinkered with LDAP, but I have since abandoned the trials.

Presently, the following warning is included in the application diagnostics:

LDAP Connection: There is an inactive LDAP configuration: s01

Navigating to Administration / LDAP/AD integration, I indeed find, in the uppermost listing, an entry called “s01”, and I find that it is indeed inactive. However, every invocation of Delete configuration merely generates a confirmation dialog box, though resulting in no deletion, even as the prompt is affirmed.

The entry remains in the listing, and the warning remains in the diagnostics.

Seemingly, I am stuck with an unused, unwanted, and problematic LDAP configuration, while finding no means of a resolution.

Naturally, I would like to purge the configuration entry, as should resolve the diagnostic warning.
