We are running MOSS 2007 with profiles coming from our active directory. One feature we use is "Audiences" which get compiled based on specific AD groups. We have problems with very few of the accounts where they do not get included in the audience. We have for example AD group of "Procurement" where 15 out of 16 users get included in the audience that uses membership in the "Procurement" group as its criteria.
It seems to be something specific to that account, but I can't see anything about the account that is distinct from any other. The AD accesss is being done by an account with full rights to read and write to AD.
Any ideas on what could be the cause? I'm not sure where even to look as the audience compliation doesn't throw any errors.
