The other thread has me wondering just exactly how often has a Schema change (especially one FROM Microsoft for a Microsoft app) actually ³broken² anything? I know back in early 2000 days, there was a lot of emphasis put on the ³dangers² of schema modification, which went all the way up into management levels in some environments, and persists to this day (it took me a month and several meetings to convince my direct reports that we didn¹t need to take precautions just to extend the schema for LCS 2005). --James

So You can have attributes which conflicts with other attributes and will result in mangled attributes values ... this was a case with Exchange and windows 2003 extensions. You can have conflicting OIDs which may prevent you from applying these extensions until you will not resolve it. Most of things related to schema extension is just FUD related stuff, which are result of some Microsoft communication back in time. We have scared customers about it and right now we are gathering fruits of it. -- Tomasz Onyszko http://www.w2k.pl/ - (PL) http://blogs.dirteam.com/blogs/tomek/ - (EN) List info : http://www.activedir.org/List.aspx List FAQ : http://www.activedir.org/ListFAQ.aspx List archive: http://www.activedir.org/ma/default.aspx
