[CentOS] openLDAP under CentOS-6

I've been hard hit by the lack of CentOS-6 documentation
mentioned in another thread.
The openLDAP setup has been changed completely between CentOS 5 and 6,
and I haven't been able to find any reasonably coherent instructions
explaining how to upgrade.
If anyone knows of such a document I should be most grateful to learn of it.

Actually I have openLDAP working (though unencrypted) with my CentOS-5 data
after a series of more or less random steps.
But I can't work out how to set the password
for the web interface at <server>/phpLDAPadmin .
Again, if anyone can tell me how to do this
I shall be most thankful.

Incidentally, I looked at the RHEL documentation on this,
<http://docs.redhat.com/docs/en-US/Red_Hat_Enterprise_Linux/
6/html/Migration_Planning_Guide/ch07s03.html>,
but it was so sparse as to be more or less useless.
