[LDAP] ominous error message in logs - user not found - without stating username

Description:

Following error message appears constantly in the Logs:

{"level":50,"time":"2021-12-15T06:27:01.796Z","pid":1,"hostname":"a98600e97b9c","name":"LDAP","err":{"type":"Error","message":"User not found","stack":"Error: User not found<br>    at server/lib/ldap/Manager.ts:166:11<br>    at /app/bundle/programs/server/npm/node_modules/meteor/promise/node_modules/meteor-promise/fiber_pool.js:43:40"},"msg":"User not found"} 

Albeit this might be valid and true, but without stating the username I would like to consider the message as not complete – and therefore as a bug.

Steps to reproduce:

Have LDAP and Users. And possibly one user which is some kind of faulty, not existing anymore, or anything like this.

Expected behavior:

State the username in the error message

Actual behavior:

username is missing in the error message

{"level":50,"time":"2021-12-15T06:27:01.796Z","pid":1,"hostname":"a98600e97b9c","name":"LDAP","err":{"type":"Error","message":"User not found","stack":"Error: User not found<br>    at server/lib/ldap/Manager.ts:166:11<br>    at /app/bundle/programs/server/npm/node_modules/meteor/promise/node_modules/meteor-promise/fiber_pool.js:43:40"},"msg":"User not found"} 

Inspect server/lib/ldap/Manager.ts around line 166, where the reported "User not found" error is raised. Reproduce the LDAP missing-user case and verify that the resulting log message identifies the affected username.
