AD Plugin only creates homes dirs on Macintosh HD not specfied sharepoint

Hi Guys, I have been working prototyping some AD-OD integration, I've scoured the web and read the guides, especially Corey's AD-OD Sandbox guide. Everything went swimmingly, I setup the home directories on both windows and osx servers and I was pretty pleased with the results. So I decided to push the limits abit. Corey's guide tells use to create the home directories for both windows and mac clients on the osxserver on the Macintosh HD/homes. That all worked, so I decided to change it alittle and redirect the sharepoint to a second volume ODDATA/homes, but before I did that I tore down the previous sharepoint, making sure I removed the tick in automount, saved and then unshared the original share on Macintosh HD/ I also deleted the directory. I then decided to try and login in as a active directory user so what would happen, Authenticated aokay, begun login process Pause, then managed prefs come across for the account (ie. dock on the left) Then message pops up saying unable to find home dir. Dock home point is ? I investigate, find there is no home folder for the user on my specified share ODDATA/homes but when I check Macintosh HD/ I found a homes/helloworld home folder on Macintosh HD created and inside that the all directories appropriate profile directories created. I spend several hours trying different things, destroying sharepoints, updating AD home path (\\leopard\homes\helloworld), remaking them, checking .. etc. and what I have found is that if the sharepoint is created on Macintosh/ everything works greats, as long as I update the AD path in AD and make the share a automount. But if you try and place the homedir on a second volume ie ODDATA, it fails, I decided to create some Open Directory users and specify their home dirs on a second volume share, wouldn't you know it, works perfectly. It's like the AD plugin is hardcoded only to make folders on / of the systems boot volume. What have I done wrong, what have I missed, it cannot be so, I have searched everywhere online and other than trying to create augment records as specified by MikeB I am stuck..... .. is that the way to go. Hoping for your feedback. Sherdian
