Problem: When attempting to access a samba share the user is getting the following errors.
session setup failed: NT_STATUS_LOGON_FAILURE
wbinfo -n <username> returns the following:
failed to call wbcLookupName: WBC_ERR_UNKNOWN_FAILURE
Cause: This can be caused if the machine is configured to use SSSD and not Winbind. Our ADBindproxy.pl script uses the Winbind.
Please reference your OS documentation on how to configure this.
For example HERE is the Redhat documentation.
Removing these packages, 'sssd-winbind-idmap' and 'sssd-libwbclient' has been shown to also resolve the issue.
