[Samba] difficulties in rid mappings in 3.0.25

[Stefanos Karasavvidis]

I use the sernet samba packages on debian sarge and have problems after
upgrading to 3.0.25 with rid mappings.

My rid configuration for 3.0.24 looks like this

	idmap backend = rid:ISC=500-100000000
	idmap uid = 500-100000000
	idmap gid = 500-100000000

after updating to 3.0.25 I get a core dump of winbind (log at the end of
the post) with these settings.

I tried to use the new configuration options, and indeed winbind doesn't
have any problems, but I have difficulties in specifying the options to
get the same mappings as before. I tried the following
	idmap domains = ISC
	idmap config ISC:default = yes
	idmap config ISC:backend = rid
	idmap config ISC:base_rid = 1000
	idmap config ISC:range = 500 - 100000000

But these result in different mappings

For example in 3.0.24 (and the old configuration) maps SID
S-1-5-21-2054584426-1363897300-1555891258-9296 to uid 9796 (I used
wbinfo -S)

In 3.0.25 and the new style configuration, maps the same SID to 8796

So the question:
what are the correct parameters to get the same mappings as before?

Thanks in advance for any help
