Package: slapd
Version: 2.4.23-7.2

Openldap refuses to use cipher TLS_RSA_3DES_EDE_CBC_SHA1 when the cipher is 
available to the system.

 Here is the output of gnutls-cli:

ldap3:/etc/ldap# gnutls-cli -l | grep TLS_RSA_3DES_EDE_CBC_SHA1
TLS_RSA_3DES_EDE_CBC_SHA1                               0x00, 0x0a      SSL3.0


and gnutls-serv

ldap3:/etc/ldap# gnutls-serv -l | grep TLS_RSA_3DES_EDE_CBC_SHA1
TLS_RSA_3DES_EDE_CBC_SHA1                               0x00, 0x0a      SSL3.0



and openldap refuses to start when this cipher is used (and only this one) :

ldap3:/etc/ldap# /usr/sbin/slapd -h ldap:/// ldaps:/// ldapi:/// -g openldap -u 
openldap -d9

[…]
TLS: could not set cipher list TLS_RSA_3DES_EDE_CBC_SHA1.
main: TLS init def ctx failed: -1
slapd destroy: freeing system resources.
syncinfo_free: rid=124
slapd stopped.
connections_destroy: nothing to destroy.



Here is the TLS relevant part of slapd.conf:

TLSCertificateFile /etc/ldap/ldap3.math.ups-tlse.fr.pem
TLSCertificateKeyFile /etc/ldap/ldap3.math.ups-tlse.fr.key
TLSCACertificateFile /etc/ldap/CNRS2-Standard.crt.full.tls
TLSCipherSuite TLS_RSA_3DES_EDE_CBC_SHA1



Here are the version of libldap, libgnutls26:

ii  libgnutls26           2.8.6-1               the GNU TLS library - runtime 
library
ii  libldap-2.4-2         2.4.23-7.2            OpenLDAP libraries
