Subject: MS-ADTS: msDS-ResultantPSO and DOMAIN_USER_RID_KRBTGT discrepancy
Hi,
I'm looking into the behaviour of msDS-ResultantPSO and found a discrepancy between the specification and the actual behaviour.
In MS-ADTS, section 3.1.1.4.5.36 msDS-ResultantPSO [1], it says the
following:
If the RID in U!objectSid is equal to DOMAIN_USER_RID_KRBTGT, then there is no value in this attribute.
I tried adding a PSO object and applying it to the krbtgt user on a Windows 2012R2 VM. Based on the spec, I would expect no msDS-ResultantPSO to be returned for the krbtgt user. However, I do see one returned, e.g.
# record 1
dn:
CN=krbtgt,CN=Users,DC=WINDOWS2012R2,DC=WIN,DC=TIM,DC=WGTN,DC=CAT-IT,DC=
CO,DC=NZ
objectSid: S-1-5-21-886655096-618523297-2770022155-502
msDS-ResultantPSO: CN=dummy-PSO,CN=Password Settings Container,CN=System,DC=WINDOWS2012R2,DC=WIN,DC=TIM,DC=WGTN,DC=CAT-IT,DC=
CO,DC=NZ
You can see the RID in the objectSid is 502, which is DOMAIN_USER_RID_KRBTGT.
Could you please clarify which is incorrect - the specification or the Windows behaviour? Or have I misunderstood something?
Thanks,
Tim
