Here comes version 3:

1.) change lp_sam_backend syntax to sam backend = 
plugin[|domain_name][:options] this was needed as ',' is a list 
seperator. The syntax is probably going to change again soon, but not 
tonight

2.) Added some DEBUG(). They are still in a total mess though

3.) I've actually tested the parsing code now and fixed (hopefully) all 
of the sig_segv. i.e. it should work now


To compile this patch via bin/samtest, you need a change in the Makefile 
so that samtest includes passdb/secrets.o and passdb/machine_sid.c

> Here comes the next version with the following changes:

> 1.) use SAM_ASSERT() some more
> 2.) implement context_sam_update_domain I forgot last time
> 3.) change the way context_sam_update_* and context_sam_delete_* find 
> their sam_methods. Use current_sam_methods from the handle

>> Hi,
>>
>> This patch is a combination of patches to the sam.
>>
>> 1.) change sam_init() to include a domain sid as an in parameter. It 
>> is used to tell the backend module for which domain it is responsible.
>>
>> 2.) implement the rest of the context_sam_* functions
>>
>> 3.) several style and debug cleanups
>>
>> 4.) change the loading routines of the sam backend parameter from 
>> smb.conf. The format is now sam backend = 
>> sam_moduleA[,domain_nameA][:options] 
>> sam_moduleB[,domain_nameB][:options] 
>> [sam_moduleB,builtin_domain[:options]]
>>
>>
>> The patch compiles, but is untested so any coments are welcome.
