[Samba] upgraded to samba-3.0.23c = continous password prompts on shares

[Elvar]

Since upgrading to samba 3.0.23c when I try and access the samba shares 
it continually prompts me for a username and password. The samba server 
has been joined to a win2k3 domain and should be allowing access based 
on the windows domain accounts like it used to be doing, but that is no 
longer working.

Any help would be greatly appreciated.


Kind regards,
Elvar
