I am able to reproduce this issue when downgrade the openldap package from 2.4.40-8.el7 to 2.4.39-6.el7.

It is happening because some packages are dependent on openldap package and when we upgrade or downgrade the openldap package, we should also upgrade or downgrade its dependent packages. But here using "yum update openldap -y" command we are upgrading openldap and its dependent packages and using "yum downgrade localinstall /home/centos/openldap-2.4.39-6.el7.x86_64.rpm" we are only downgrading openldap package. So, we are facing this issue.

You can resolve this issue using below steps:

1. rpm -ev openldap --nodeps
2. wget http://vault.centos.org/7.1.1503/os/x86_64/Packages/openldap-2.4.39-6.el7.x86_64.rpm
3. rpm -ivh openldap-2.4.39-6.el7.x86_64.rpm
