Konica Minolta LDAP 50 Error

What usually causes it
- The bind account may be valid but restricted from the requested search or attribute.
- Directory permissions or organizational-unit access may have changed.
- The printer may be searching a base/path that the account is not allowed to read.
What to try
Confirm the LDAP login itself is working
Code 50 is a permissions result, so avoid replacing credentials unless login is also failing.
Check the search base and requested operation
Verify the saved directory scope is the one the account is supposed to access.
Have the directory administrator review minimum permissions
Grant only the directory-read/search access required for the printer workflow.
Retry the original lookup
Repeat the address search or authentication operation after access is corrected.
After each corrective action
Retry the same operation that produced LDAP 50. If it now works, stop there rather than changing unrelated printer, network, or service settings.
If the code returns
If the code returns, the server is still denying the requested LDAP operation. Server logs are usually more useful than restarting the printer repeatedly.
When service may be needed
Do not broaden directory privileges beyond what the workflow needs. LDAP permissions should be handled by the directory administrator.
Continue with guided troubleshooting
If the printer still is not working after the reviewed checks, carry this verified error context into the guided troubleshooter.
