Bug#836885: [Pkg-openldap-devel] Bug#836885: Bug#836885: please stop building against Heimdal

[Ryan Tandy]

Unfortunately, this isn't as easy as just removing the build-dep, 
because after upgrading:

57f71842 olcSmbK5PwdEnable: value #0: smbk5pwd: <olcSmbK5PwdEnable> module 
"olcSmbK5PwdEnable" only allowed when compiled with -DDO_KRB5.
57f71842 config error processing olcOverlay={0}smbk5pwd,olcDatabase={1}mdb,cn=config: 
<olcSmbK5PwdEnable> handler exited with 1
Looks like we'll have to remove "olcSmbK5PwdEnable: krb5" during 
upgrades.
