[Samba] Winbind crashes in 3.026a using rid

[Jens Nissen]

Winbind 3.026a crashes when reading out user information with wbinfo
using the idmap/rid module.
The tdb module works without crash (tested by exchanging the uncommented
and commented lines in the following fragment from smb.conf).

I configured rid as follows:
[global]
#  idmap uid=1000-60000
#  idmap gid=1000-60000
idmap domains=TRUSTEDDOMAINS
idmap config TRUSTEDDOMAINS:readonly=yes
idmap config TRUSTEDDOMAINS:backend=rid
idmap config TRUSTEDDOMAINS:default=yes
idmap config TRUSTEDDOMAINS:base rid=1000
idmap config TRUSTEDDOMAINS:range=1000 - 60000

In the log (level 10) I find the last lines before winbindd dies:

What is additionally strange and annoying: I had to compile rid manually
(with 'make lib/rid.so'), the build process simply forgets to compile or
install rid.so. Are there any other shared libraries which I have to
compile and install manually? I could not find any documentation about this.
