Enter LDAP Settings like this:

      │ Base DN: ou=People,dc=osgeo,dc=org_______________ │
authconfig sets a number of PAM-related items for us, but it does a poor job of setting up the LDAP configuration.  We are going to edit /etc/ldap.conf and change it to look like this:
  BASE dc=osgeo, dc=org
  URI ldaps://ldap.osgeo.org
  pam_groupdn cn=telascience,ou=Shell,dc=osgeo,dc=org
  nss_base_passwd ou=People,dc=osgeo,dc=org
  nss_base_shadow ou=People,dc=osgeo,dc=org
  nss_base_group  ou=Group,dc=osgeo,dc=org
  ldap_version 3
  TLS_REQCERT demand
  TLS_CACERTDIR /etc/openldap/cacerts
  pam_password md5
After editing /etc/ldap.conf, we need to link /etc/openldap/ldap.conf to use that one, instead of its own. 
  mv /etc/openldap/ldap.conf /etc/openldap/ldap.conf.original
  ln -s /etc/ldap.conf /etc/openldap/ldap.conf
Next, you need to scp the DigiCertCA.crt from one of the existing blades to the machine you are enabling:
  scp /etc/openldap/cacerts/DigiCertCA.crt hobu@mynewblade:/home/hobu
Once there, mv it into the same location:
  sudo mv DigiCertCA.crt /etc/openldap/cacerts
Once this is setup people can be added to the OSGeo LDAP Shell group by adding them at the following url for those already in the group:
Sudo access must be added locally per server.

It seems that the LDAP entries require an email attribute that bugzilla can use for sending email, but generally speaking this seems like a well supported option for bugzilla.  I do wonder if there is an option for users not in LDAP to create accounts in bugzilla for the purpose of submitting bugs.  I think this is desirable or even necessary!
