Upgrading Alpha9 install to master

[Brian Marshall]

Hello, long time samba4 user (going back to the TPs) here. I stopped 
keeping up with master around Alpha9, since everything was stable for my 
small domain.
However, things have changed with my latest round of hardware upgrades, 
and I can't successfully use new machines on the domain. I can join, but 
then wbinfo doesn't work, and I can't log on with SSO (tons of IDMap 
errors).
I'd like to be able to upgrade to a newer version of Samba to see if 
that fixes my problems, but no matter what version I try, 
upgradeprovision just hoses my install. I've tried 
Alpha10,11,13,14,15,16 and 17 as well as master. They all build properly 
and segfault at different places. The Alphas segfault looking for ldb 
files (and creating them just makes a segfault farther along, which 
hoses the install), and master segfaults trying to parse the 
Configuration CN. I've pasted the output below:

To track the USNs modified/created by provision and upgrade proivsion,
  the following ranges are proposed to be added to your provision sam.ldb:
lastProvisionUSN: 10-3274;f04ab2a7-99eb-45d9-8058-57caaaaffd8b

We recommend to review them, and if it's correct to integrate the 
following ldif: /tmp/usnprov8Efldl.ldif in your sam.ldb
You can load this file like this: ldbadd -H 
/usr/local/samba/private/sam.ldb /tmp/usnprov8Efldl.ldif

Once you applied/adapted the change(s) please restart the 
upgradeprovision script
galadriel:/usr/src/samba-master# /usr/local/samba/bin/ldbadd -H 
/usr/local/samba/private/sam.ldb /tmp/usnprov8Efldl.ldif

Is there any way for me to dump out the users/computers from my current 
domain and reload them into a freshly provisioned one?
I'd rather not have to unjoin/rejoin all the computers and recreate all 
the users manually and have to deal with profile problems or fudging 
SIDs. I tried to dump out LDIFs with JXplorer and remerge into a freshly 
provisioned server, but couldn't manage it for some reason.
Any help would be greatly appreciated. Please let me know if there is 
any other info I can provide.
Thanks!
