Name service switch broken on samba 4 RC5?

[Bernard Bos]

Hi,

 

I did recently an fresh install of our Samba testing environment with
samba Release Canidate 5. 

I noticed that the getent isn't working anymore as it should be. It
doesn't give any users or groups back from winbind. 

 

The distribution we use is CentOS 6.3.

 

I installed /usr/local/samba/lib/libnss_winbind.so.2 to
/lib/libnss_winbind.so.2

ln -s /lib/libnss_winbind.so.2 /lib/libnss_winbind.so

/sbin/ldconfig -v | grep winbind

 

nsswitch.conf: 

...

passwd:     files winbind

shadow:     files

group:      files winbind

...

 

wbinfo -u and wbinfo -g 

does give the proper result. 

 

We had this working with RC 3.

Am I missing something in relation to the newer RC versions?

 

What I now also noticed, is that running wbinfo -u takes a long time to
return the users. 

While running this command samba has a high CPU load. I don't know for
sure if this differ with previous releases of samba 4 

 

On samba 4:

date ; wbinfo -u | wc -l ; date

Fri Nov 16 11:30:56 CET 2012

361

Fri Nov 16 11:31:18 CET 2012

 

On a samba 3 environment:

date ; wbinfo -u | wc -l ; date

Fri Nov 16 11:36:09 CET 2012

461

Fri Nov 16 11:36:09 CET 2012

 

Kind Regards,
