Hi, folks
I am using the APIs from openldap and recently run into a problem which upset me. Following is the framework of the function. ldaps_func() { LDAP* ld = NULL; char * uri ="ldaps://xxx.xxx.xxx:636"; ..... ldap_set_option(...); //using LDAP v3 ldap_set_option(...); // set LDAP_OPT_X_TLS_REQUIRE_CERT to deman ldap_set_option(...); // set LDAP_OPT_X_TLS_CACERTDIR to/tmp/ldapsCA/
If you really want the TLS context recreated with each iteration I think you can just call: ldap_set_option( NULL, LDAP_OPT_X_TLS_NEWCTX, LDAP_OPT_ON); after the above calls.
ldap_initialize(&ld, uri); ..... ldap_simple_bind(.....); ldap_search_ext(...); ...... ldap_unbind(ld); ..... return 0; } Above function is called in a while loop to authenticate users to a LDAPS server when authentication request comes up. This function works fine. BUT after one successful authentication, if I delete CA certificates of server's certificate under /tmp/ldapsCA/, subsequent authentications will STILL succeed. If restart this daemon, no authentication will succeed, because CA certificates under /tmp/ldapsCA/ has been deleted. Why I delete CA certificates under /tmp/ldapsCA/? I just want to simulate "certificate change". Is the openssl library cache someting??
Any one has any ideas about this? I will really appreciate it.
