Title: #5508: ipa-sam: return NetBIOS domain name instead of DNS one
Action: opened
PR body:
"""
[MS-NRPC] section 2.2.1.4.11 requires that the structure
NETLOGON_VALIDATION_SAM_INFO has the same values as defined in the
KERB_VALIDATION_INFO structure from [MS-PAC] section 2.5.
Samba's netr_SamBaseInfo.domain_name corresponds to
KERB_VALIDATION_INFO.LogonDomainName and must be a NetBIOS name of the
domain, not a DNS one.
Failure to provide NetBIOS name here actually breaks
netr_LogonSamLogonEx call issued by IPA-enrolled Samba domain member
which is confused by the returned value:
