See that + on the end of the mode field?  That means there are ACLs in
affect; and my guess is one of the ACLs allows your uid to change to
that directory even though the owner of the directory does not have the
same permissions.

Yep - just as I said.  The actual uid/gid owner (which is probably being
treated as -1 meaning your /etc/group and /etc/passwd are incomplete) is
different than the 'root', 'SYSTEM', or 'Users' groups, all of which
have an additional ACL allowing you to chdir into the directory.
