Sun Java System Directory Server Enterprise Edition 6.2 has been released with Sun Java Enterprise System 5 Update 1 about two weeks ago.
Now the full install and the Zip archives can be downloaded from the DSEE Download page.
On a side note, it has been reported a couple of times, that Directory Server failed to restart after installing the 6.2 patch. It seems that it is linked with a specific hot-fix being applied to the Directory Server binaries prior to install 6.2 patch. If you have applied a hot-fix to DS 6 and want to install DS 6.2 patches, make sure that in the /opt/SUNWdsee/ds6/lib and /opt/SUNWdsee/ds6/lib/sparcv9 directories, the libslapd.so is a symbolic link to libslapd.so.1 (and the later is in fact the real dynamic library).
