[Samba] Problem with [homes] under 3.0.23x

I found another strange problem while migrating from 3.0.22 to 3.0.23x 
(with 'x' eq 'd' now):

I can't access my [homes]-share anymore - if i try, the samba-server 
prompts me for a password. What *is* working is accessing the same 
directory as [<username>]...

E.g.: \\Sambaserver\matthias works  whereas
      \\Sambaserver\homes    works *not*

Unfortunaely it is essential for some of our processes to access the 
specific homedir of each user with the same sharename. It did work 
again after downgrade to 3.0.22. This implies that I didn't change 
anything on the samba configuration. The server is a member of an 
W2k3-AD-Domain. OS is FreeBSD 5.5 and 6.2

If I look at the log-files, everything looks fairly good, the 
homes-Service is mapped to the right directory, the (Win-) Username is 
mapped to the right unix account - no obvious problems in this area.

The only problem I found in the logfiles is a failure to decrypt 
incoming ticket (I think, this is why the password request pops up) 
when I try to access the homes-share. As said before, no problems when 
accessing all the other shares (there are lots!). What is different 
when accessing the homes-share?

I tried MIT-Kerberos as well as Heimdal 0.64 (IIRC, FreeBSD base), no 
difference. This makes kind of sense to me, because *if* it's a 
kerberos-problem it should be there with 3.0.22 as well, isn't it?

The most strange thing at the end: On my workstation (FreeBSD 6.2 as 
well) it works. Same config (I checked *every line, /etc/krb5 *and* 
/usr/local/etc/smb.conf), same kerberos, also samba 3.0.23d - I have no 
idea what's going right here and wrong on the other machines. Perhaps a 
different encryption of the tickets? But how can I influence this? The 
ticket I get after 'kinit' is arcfour-encrypted - on the (not working) 
server as well as on the (working) workstation.

Any suggestions and further questions are welcome...
