Start with salt/states/ldap.py and the managed entry point shown in the traceback; trace why salt lacks ldap3.connect after the 3005.5-2 upgrade. Reproduce the failure with the supplied state.highstate command and compare the relevant behavior between the reported package versions. Done means ldap.managed no longer raises this KeyError for the supplied configuration.
