Hi, I have tried upgrading to Samba-3.0.13 and we are having problems. When Samba is started it reports that it has joined the domain successfully. Although wbinfo -u and wbinfo -g returns user and group information when a user tries to connect to the share they are just presented with a logon dialogue box and the share is inaccessible. The logs in /usr/local/samba/var have the following problems. log.winbindd [2005/04/09 14:11:58, 1] nsswitch/winbindd.c:main(864) winbindd version 3.0.13 started.

We are authenticating to an NT4.0 sp6 PDC. The OS is sparc Solaris 8 running Veritas Cluster. The cluster initiates a start script to run Samba.
