Bug 1034265

Description of problem:
7-bit check plugin should deny all operations, that would change tracked attribute to value that is not 7-bit clean. However, MODRDN operation is not checked, which allows us to change the tracked attribute to value, that would normally be refused.

Version-Release number of selected component (if applicable):
389-ds-base-1.2.11.15-29.el6.x86_64

How reproducible:
always
