Hello,
when I try to connect from Centos7 machine to the ldap server and
there is no NSS export in the dirsrv file, it crashes. I am not using
the cipher option in this case.:
$ openssl version; rpm -qa openssl

Same happens from Fedora23 and Centos6
F23:
$ openssl version;rpm -qa openssl

$ openssl version; rpm -qa openssl
OpenSSL 1.0.1e-fips 11 Feb 2013
openssl-1.0.1e-30.el6_6.5.x86_64
From Centos5 is OK:
$ openssl version;rpm -qa openssl
OpenSSL 0.9.8e-fips-rhel5 01 Jul 2008
openssl-0.9.8e-32.el5_11
with "export NSS_DISABLE_HW_GCM=1", there are no crashes, with and
without the cipher option. Moreover, with the cipher option it says:
CONNECTED(00000003)

With "export NSS_DISABLE_HW_AES=1" there are no crashes.
I have a secondary LDAP server, who has the following software versions:
389-admin-1.1.35-1.el6.x86_64
389-adminutil-1.1.19-1.el6.x86_64
389-ds-console-1.2.6-1.el6.noarch
389-ds-1.2.2-1.el6.noarch
389-dsgw-1.1.11-1.el6.x86_64
389-console-1.1.7-1.el6.noarch
389-admin-console-1.1.8-1.el6.noarch
389-ds-console-doc-1.2.6-1.el6.noarch
389-ds-base-1.2.11.15-48.el6_6.x86_64
389-ds-base-libs-1.2.11.15-48.el6_6.x86_64
389-admin-console-doc-1.1.8-1.el6.noarch
nss-3.16.2.3-3.el6_6.x86_64
It was OK with all the stuff I was throwing on it.
After the update to the following versions:
389-admin-1.1.35-1.el6.x86_64
389-adminutil-1.1.19-1.el6.x86_64
389-ds-console-1.2.6-1.el6.noarch
389-ds-1.2.2-1.el6.noarch
389-dsgw-1.1.11-1.el6.x86_64
389-ds-base-1.2.11.15-68.el6_7.x86_64
389-console-1.1.7-1.el6.noarch
389-admin-console-1.1.8-1.el6.noarch
389-ds-console-doc-1.2.6-1.el6.noarch
389-ds-base-libs-1.2.11.15-68.el6_7.x86_64
389-admin-console-doc-1.1.8-1.el6.noarch
nss-3.19.1-8.el6_7.x86_64
it started crashing.
Many thanks for your help
