Wiki permissions.

Hi,

Situation is: I want to migrate an existing Wiki on Lion 10.7.5 to Mountain Lion 10.8.2

Presently: I thought I was doing alright and followed http://support.apple.com/kb/HT5082.

Problem: Unfortunately I didn't read this kb through properly and missed the last paragraph *Migrating wikis does not migrate users or groups. These instructions are intended for use with the new serveris bound to the same directory server as the previous server" However this isn't the case and now i need to somehow change wiki permissions as I'm unable to log in.

Thanks
