Hi all,
Is the suffix dc=example,dc=com in tree is a valid rdn ?
A suffix is an RDN of it's own entry because it sits at the root and is relative to itself. However, if your suffix was dc=com, and you created a subentry called dc=example, then it's a different story. So, it just depends on how you construct your suffix.
and whether the drawing http://www.zytrax.com/books/ldap/ch2/dit-dn-rdn.pngis correct?
All in all, everything I have seen in zytrax is high quality info.
