accountID lastname truncation

I use an activsyncform to load users.

I was quite surprised to see the lastname being truncated to 9letters, when there is no rule to do so.(accountId=lastname+firstname firstinitial.

I checked the accountId policy and is set to 20.

And the rule doesnt say anything about truncating to 9 letters.

Do anybody know if I shoudl be looking at something else.
