Yes, I am talking about 389ds as is integrated in FreeIPA (would be silly to post completely non-IPA questions to this list...). I am running FreeIPA 4.1.4 on CentOS 7.1 and RC4 is enabled on port 636 no matter what I do.
I am running "CentOS Linux release 7.1.1503 (Core)" Relevant Packages: freeipa-server-4.1.4-1.el7.centos.x86_64 389-ds-base-220.127.116.11-1.el7.centos.x86_64 nss-3.19.1-5.el7_1.x86_64 openssl-1.0.1e-42.el7.9.x86_64 LDAP setting (confirmed that in error.log there is no menition of RC4 in list of ciphers): nsSSL3Ciphers: -rc4,-rc4export,-rc2,-rc2export,-des,-desede3,-rsa_rc4_128_md5,-rsa_rc4_128_sha,+rsa_3des_sha,-rsa_des_sha,+rsa_fips_3des_sha,+fips_3des_sha,-rsa_fips_des_sha,-fips_des_sha,-rsa_rc4_40_md5,-rsa_rc2_40_md5,-rsa_null_md5,-rsa_null_sha,-tls_rsa_export1024_with_rc4_56_sha,-rsa_rc4_56_sha,-tls_rsa_export1024_with_des_cbc_sha,-rsa_des_56_sha,-fortezza,-fortezza_rc4_128_sha,-fortezza_null,-dhe_dss_des_sha,+dhe_dss_3des_sha,-dhe_rsa_des_sha,+dhe_rsa_3des_sha,+tls_rsa_aes_128_sha,+rsa_aes_128_sha,+tls_dhe_dss_aes_128_sha,+tls_dhe_rsa_aes_128_sha,+tls_rsa_aes_256_sha,+rsa_aes_256_sha,+tls_dhe_dss_aes_256_sha,+tls_dhe_rsa_aes_256_sha,-tls_dhe_dss_1024_rc4_sha,-tls_dhe_dss_rc4_128_sha Slapd "error" log showing no ciphersuites supporting RC4: [23/Sep/2015:08:51:04 -0600] SSL Initialization - Configured SSL version range: min: TLS1.0, max: TLS1.2 [23/Sep/2015:08:51:04 -0600] - SSL alert: Cipher suite fortezza is not available in NSS 3.16.
