Title:
  apparmor stops /var/run/ldapi from being read causing ldap to fail

Status in openldap package in Ubuntu:
  Fix Released
Status in openldap source package in Utopic:
  Won't Fix
Status in openldap source package in Vivid:
  Fix Released

Bug description:
  [Impact]

  * Changes to AppArmor's unix socket mediation in utopic and later
  require servers to have 'rw' file permissions on socket paths,
  compared to just 'w' previously.

  * This bug breaks any application that tries to communicate with slapd
  via the ldapi:// scheme, for example heimdal-kdc.

  * The recommended way to configure slapd in Ubuntu is to authenticate
  via SASL EXTERNAL over the ldapi socket. This bug prevents online
  configuration of slapd (via ldapmodify) in the default setup.

  [Test Case]

  apt-get install slapd
  ldapwhoami -H ldapi:// -QY EXTERNAL

  Expected result:
  dn:gidNumber=0+uidNumber=0,cn=peercred,cn=external,cn=auth

  Actual result:
  ldap_sasl_interactive_bind_s: Can't contact LDAP server (-1)

  [Regression Potential]

  * Extremely low potential for regression. No code changes, only
  granting an additional permission on contents of two directories. The
  worst possible regression is that slapd might be permitted to read
  some files it shouldn't, but having such files in /run/{slapd,nslcd}
  seems unlikely.
