Second short name acess permissons improperly on Wiki server after update to 10.6.8 v1.1

Hi,

We update our Wiki server to Mac OS X 10.6.8 v1.1 last weekend. It is running 10.6.5 before update.

Every thing working fine but second short name.

In ODM all user have three name for example:

Full name: Johnny Liu

Short name:johnnyliu

Second short name:johnny.liu

Johnny Liu and johnnliu access permission properly on Wiki pages.

But the second short name access permission incorrect on Wiki pages

Thanks
