Full_Name: Jan Vcelak Version: git master OS: Linux URL: ftp://ftp.openldap.org/incoming/jvcelak-20120828-tls-do-not-reuse-tls_session-if-hostname-check-fails.patch Submission from: (NULL) (209.132.186.34)

If multiple URIs are specified when creating LDAP connection, the connection to the first one succeeds but the hostname verification fails, *tls_session is not dropped, but reused when connecting to the second server.

This is a problem with Mozilla NSS backend because another handshake cannot be performed on the same file descriptor and SSL_ForceHandshake() will hang. From this reason, hostname checking was moved into ldap_int_tls_connect() before connection error handling.

I have verified for all backends (OpenSSL, GnuTLS, MoznSSS) that this fix does not break hostname verification and that this bug does not present.
