Hi everybody I have setting my ldap server. But I created an certificate with the following command: cd /usr/share/ssl/certs; make ldap.pem Then edit slapd.conf file a insert the following lines: TLSCipherSuite HIGH:MEDIUM:+SSLv2 TLSCACertificateFile /usr/share/ssl/certs/ldap.pem TLSCertificateFile /usr/share/ssl/certs/ldap.pem TLSCertificateKeyFile /usr/share/ssl/certs/ldap.pem I restart the service. Then, I run the comando authconfig and I select ldap with tls. I review the logs ldap server a thrown the following: Mar 5 11:54:38 eucalipto slapd[711]: conn=13 fd=14 ACCEPT from IP= 172.16.12.160:33935 (IP=0.0.0.0:389) Mar 5 11:54:38 eucalipto slapd[711]: conn=13 op=0 STARTTLS Mar 5 11:54:38 eucalipto slapd[711]: conn=13 op=0 RESULT oid= err=0 text= Mar 5 11:54:39 eucalipto slapd[711]: conn=13 fd=14 closed (TLS negotiation failure) I need you help.
