LDAP Error "User Name Not Found"

Question

When users try to log onto my web app, an LDAP error, code 49 data 525, occurs, which means username not found. LDAP Errors

I don't know if my resource account, which authenticates to my LDAP server, has a bad username OR whether it's the users trying to log onto my system.

How can I figure this out?

For my issue, I had incorrectly entered the DN of the particular LDAP user. I had failed to escape the comma in CN=Smith\, John.

After adding the backslash, I got another LDAP error error code 49 data 52e, whcih means bad username & password.

Nonetheless, it was an escaping issue.
