There's a related question with an answer at apache auth: combination of LDAP and htpasswd but I'd like to expand on that.
I want to allow users if they are in the htpasswd file or if they are in LDAP and members of a valid group.
So Require valid-user from the other question is not strict enough as it would allow anyone from LDAP.
According to http://www.yellow-bricks.com/2010/04/08/aligning-your-vms-virtual-harddisks/ it is important to align the virtual hard drives of virtual machines for performance. I'm running virtual machines in an environment built on Debian, KVM and LVM.
What steps should be taken to get alignment right when installing a host node?
How can the alignment be checked on an already installed node?
Can the alignment be altered without re-installation? How?
