Thanks for making this work i had troubles yesterday porting the IRPC stuff. I made a test for this implementation and i pushed it to http://git.samba.org/?p=anatoliy/anatoliy.git;a=shortlog;h=refs/heads/nadya-fsmo-fixed-test
There is the following problem with that test, it works with windows though:
1. schedule a partition pull with extended op
2. receive getncchanges with extended op, process it and return to sender
3. receive another getncchanges with extended op, process it and return to sender
4. callback is called for the 2nd but not for the first call
5. second call fails because there on step 3 we have already changed the role.
The transfer goes well but the second extended op is totally unexpected and shows error.
To reproduce this you can pull and run make test TESTS=fsmo
