Title:
  Incorrect directory for (lib)krb5 plugins

Status in krb5 package in Ubuntu:
  Triaged
Status in krb5 package in Debian:
  Fix Released

Bug description:
  The libkrb5-3 package built from the krb5 source hints at a (lib)krb5
  plugin directory like this:
  debian/libkrb5-3.dirs.in:usr/lib/${DEB_HOST_MULTIARCH}/krb5/plugins/krb5
  debian/libkrb5-3.lintian-overrides:libkrb5-3:
  package-contains-empty-directory */plugins/krb5/

  The correct (lib)krb5 plugins directory, however, is:

  /usr/lib/${DEB_HOST_MULTIARCH}/krb5/plugins/libkrb5

  This can be verified in the krb5 source:
  $ grep plugins/libkrb5 -r src
  src/lib/krb5/os/locate_kdc.c:                                 LIBDIR
  "/krb5/plugins/libkrb5",
  src/lib/krb5/os/locate_kdc.c:static const char *objdirs[] = { LIBDIR
  "/krb5/plugins/libkrb5", NULL };

  As well as in the built library:
  $ strings /usr/lib/x86_64-linux-gnu/libkrb5.so.3|grep plugins
  /usr/lib/x86_64-linux-gnu/krb5/plugins/authdata
  /usr/lib/x86_64-linux-gnu/krb5/plugins
  plugins
  /usr/lib/x86_64-linux-gnu/krb5/plugins/libkrb5

  This also briefly introduced a bug in the ubuntu and debian sssd packages,
  which assumed .../plugins/krb5 was the correct path:
  https://bugs.launchpad.net/ubuntu/+source/sssd/+bug/1664566

  In debian it was fixed in commit e6c4e91473e75f0ddc917a24f4d561fab9900939:
  commit e6c4e91473e75f0ddc917a24f4d561fab9900939

      rules, common.install: Fix sssd_krb5_locator_plugin install path. (LP:
  #1664566)

  
  There is no immediate impact to the libkrb5-3 package itself, since MIT
  kerberos does not ship any libkrb5 plugin at the moment and it is an empty
  directory. It should be fixed, though, to avoid inducing similar bugs in
  the future.
