Fixed In Version: 2.4.40-4
Doc Type: Bug Fix
Doc Text:
After upgrading the system from Red Hat Enterprise Linux 6 to Red Hat Enterprise Linux 7, symbolic links to certain libraries unexpectedly pointed to locations belonging to the openldap-devel package. If the user uninstalled openldap-devel, the symbolic links were broken and the "rpm -V openldap" command sometimes produced errors. With this update, the symbolic links no longer get broken in the described situation. If the user downgrades openldap to version 2.4.39-6 or earlier, the symbolic links might break. After such downgrade, it is recommended to verify that the symbolic links did not break. To do this, make sure the yum-plugin-verify package is installed and obtain the target libraries by running the "rpm -V openldap" or "yum verify openldap" command.

....L....    /usr/lib64/libldap_r-2.4.so.2
....L....    /usr/lib64/libslapi-2.4.so.2

when upgrading to openldap openldap-2.4.40-2.el7 and the devel package is installed.

Version-Release number of selected component (if applicable):
openldap-2.4.40-2.el7

How reproducible:
always

Steps to Reproduce:

1/ Firs a demonstration with package versions RHEL-7.0 < RHEL-7.1 to show it worked as expected:

[root@rhel70 ldap]# rpm -qa openldap\*

2/ The issue appears when upgrading from RHEL-7.1 to RHEL-7.2:

[root@rhel70 ldap]# rpm -Uvh ~/ldap/openldap-2.4.39-6.el7/openldap-2.4.39-6.el7.x86_64.rpm ~/ldap/openldap-2.4.39-6.el7/openldap-devel-2.4.39-6.el7.x86_64.rpm

....L....    /usr/lib64/libldap_r-2.4.so.2
....L....    /usr/lib64/libslapi-2.4.so.2

3/ The issue seems to be that /usr/lib64/liblber-2.4.so.2 points to symlink liblber.so what is owned by openldap-devel!

[root@rhel70 ldap]# ll /usr/lib64/liblber*
lrwxrwxrwx. 1 root root    10 Jun 10 15:50 /usr/lib64/liblber-2.4.so.2 -> liblber.so
-rwxr-xr-x. 1 root root 61848 Jun  3 10:40 /usr/lib64/liblber-2.4.so.2.10.3
lrwxrwxrwx. 1 root root    21 Jun 10 15:50 /usr/lib64/liblber.so -> liblber-2.4.so.2.10.3
[root@rhel70 ldap]# rpm -qf /usr/lib64/liblber-2.4.so.2
openldap-2.4.40-2.el7.x86_64
[root@rhel70 ldap]# rpm -qf /usr/lib64/liblber-2.4.so.2.10.3
openldap-2.4.40-2.el7.x86_64
[root@rhel70 ldap]# rpm -qf /usr/lib64/liblber.so
openldap-devel-2.4.40-2.el7.x86_64

4/ And this may cause real problem not only some warning, when openldap devel is suddenly removed:

[root@rhel70 ldap]# rpm -ev openldap-devel
Preparing packages...
openldap-devel-2.4.40-2.el7.x86_64
[root@rhel70 ldap]# ll /usr/lib64/liblber*
lrwxrwxrwx. 1 root root    10 Jun 10 15:50 /usr/lib64/liblber-2.4.so.2 -> liblber.so
-rwxr-xr-x. 1 root root 61848 Jun  3 10:40 /usr/lib64/liblber-2.4.so.2.10.3

Comment 1 Patrik Kis 2015-06-10 10:03:58 EDT 
This is a regression with serious impact on the system. In short, when a system is upgraded and the openldap-devel package is removed (what is perfectly valid operation), the system will be in in inconsistent state.
Comment 3 Matus Honek 2015-06-23 04:25:18 EDT 
As correctly stated by Patrik, the links point to wrong files, therefore rpm -V complains those files are broken.
The cause is /sbin/ldconfig which was present at multiple places in the openldap.spec file and which made the links with filename equal to the SONAME of the library to point to links of filename equal to a base name of a library. That means a problem would occur, as also correctly stated by Patrik, on removal of the link caused by removing openldap-devel package.
The problem seems to be in multiple packages and each one solves it its way. See a discussion [1] for example.

Because all the links for the ${_libdir} are provided as files by packages themselves, I drop the calls of /sbin/ldconfig from the .spec file and call it only where required. See git-diff [2].

Comment 5 Patrik Kis 2015-06-24 08:22:21 EDT 
Although rpm -V does not report error when upgrading to the latest package, I found two cases when this is still failing:

1/ Downgrade

Comment 6 Matus Honek 2015-06-29 12:02:20 EDT 
Fixing a wrongly called ldconfig by [1], so that it does what was intended.

Due to the calls to ldconfig in versions 2.4.39-6 and older a downgrade will result to rpm -V complaining in specific situations, that cannot be fixed by fixing future versions. Therefore an attention should be paid on where the links in /usr/lib (/usr/lib64 respectively) are pointing to. See `rpm -V openldap', or `yum verify openldap' with yum-plugin-verify installed, after downgrade for the target libraries.
