Attribute Setup screen and changed "User ID" to samaccountname (it previously was using samAccountName, I think it was), and as a result the user name is considerably shorter when checked on the LDAP User's own Details screen. So, in another browser, I tried once again to login to a page to which I know my LDAP User account has Write Permission, using my samaccountname as my username. But, unfortunately, it's the same result: Invalid username or password entered. I still can't get in using my LDAP User credentials. And I had such high hopes for a few seconds there... What on earth can I be doing wrong? Is there anything left to try? This is all a bit outside my experience, as you can probably guess, Ash...! (Incidentally, when I go to an LDAP User asset's Linking screen, it displays nothing, i.e. no Linked Parent/s. Does that seem right?) Thanks for your enormous patience with me, Ash, and sorry for taking so much of your time.
