Hi Louis, 

The 'msNPAllowDialin' is a standard AD attribute:

cn: msNPAllowDialin
ldapDisplayName: msNPAllowDialin
attributeId: 1.2.840.113556.1.4.1119
omSyntax: 1
isSingleValued: TRUE
schemaIdGuid: db0c9085-c1f2-11d1-bbc5-0080c76670c0
systemOnly: FALSE
searchFlags: fCOPY
attributeSecurityGuid: 037088f8-0ae1-11d2-b422-00a0c968f939

If you look here:


it says:

Do not modify this value directly.

But I also found this:


From which, it seems that if you don't have the attribute, you 'Control
access through remote access policy'
If you have the attribute, it can only be set to 'TRUE' or 'FALSE'
