Problem joining a domain.
Hi,
I'm running Samba/openLDAP on a FC4 and I'm trying to make it work as a
PDC. I installed all the software using yum instead smbldap-tools.
I've done all the configuration but, when I try to join a Windows XP
Professional named 'pc4' to the domain it fails with "Error joining the
domain OPENWIRED. Username not found". And no machine account is created
under ou=Computers,dc=openwired,dc=net
If I run /usr/local/sbin/smbldap-useradd -w 'pc4$' it works OK.
smbd.log at the end.
When I start SAMBA it binds...

R and S-Plus got the different results of principal component analysis from SAS, why?
...fferent.
First, I list my results from R,S-PLUS and SAS/STATA/SPSS, and then show
the original dataset, hoping sb. to try and explain it.
SAS,STATA,and SPSS have the same results, so i put them together. From
their results, we see that the absolute values of coeffiecient are same, but
PC1,PC2,PC4,PC5 and PC6 in R have the opposite sign on the coeffiecnts
contrast with SAS, and PC4,PC5 in S-PLUS have the opposite sign on the
coeffiecnts contrast with SAS. Curiously, I got the same results amont all
these software using my another dataset.
