Public bug reported:

Binary package hint: samba

Hi 
I've just intalled Ubuntu Server 8.04 LTS in order to run Samba/Ldap PDC but I,ve encountered an error which looks like a bug 3905 that was fixed in samba 3.0.23 according to changelog. I tried two different configuration both ends in the same moment with an error. first one is exact copy of solution from chapter 5 from "Samba3 by example". Second one based on SAMBA-LDAP Howto from smbldap-tools. Slapd is empty but working gives correct DSE responses.  but when I lunch samba smbd crashes with this information in logs:

if I add 
winbind nested groups = no

I can start smbd daemon but it is workaround not proper solution for server.  
The same configuration on US 9.04 works without problems. Does anybody meet this error.
