LDAP Query Returning More Than One Result

[kakoneh]

I'm experiencing Jupyterhub Login failure when LDAP query is configured to do a full domain search and returns multiple result. We're doing a full domain search of our organization because Jupyterhub users spans multiple OUs. The same LDAP query in Powershell returns a single result or user. All tips and suggestions are welcome... Thanks in advance...

The configuration we're using looks like below:

• c.LDAPAuthenticator.user_search_base = 'DC=xxxx,DC=com'
• c.LDAPAuthenticator.user_search_filter = '(&(objectCategory=person)(objectClass=user)(sAMAccountName={username}))'

Please fine the error response string below(Replaced secrets with 'x')

@Armadik, thanks for your response... One more question on this, as I have already installed Jupyterhub on Redhat Linux 8, how do I update Jupyterhub or LDAP to pull in these new fixes?

@Armadik also, the commit/Code Change you pointed me to was never merged...
