[PATCH v3 2/7] adsldp: split the user into a domain and a username, where possible

[Damjan Jovanovic]

Extensive tests show that, for the secure authentication case,
adsldp's IADsOpenDSObject::OpenDSObject() and wldap32's ldap_bind_s()
both agree on success/failure and generate equivalent network packets,
only when IADsOpenDSObject::OpenDSObject() splits up "domain\user"
style usernames into SEC_WINNT_AUTH_IDENTITY_W's Domain and User, while
ldap_bind_s() receives them already split up like that, regardless of
the domain's format (domain, domain.local) or even correctness.
