[Samba] Smbd startup failure caused by a failure to create an NT token for the guest account
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.
