If curl is built with openldap support (USE_OPENLDAP=1) but does not have also some other protocol (IMAP/SMTP/POP3) enabled that brings in Curl_sasl_* functions, then the build will fail with undefined references to various symbols: ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_decode_mech' ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_parse_url_auth_option' ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_cleanup' ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_can_authenticate' ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_continue' ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_start' ld: ../lib/.libs/libcurl.so: undefined reference to `Curl_sasl_init' This was tracked down to these functions bein used in openldap.c but defined in curl_sasl.c and then forward in two vauth/ files to have a guard against a set of #define configurations that was now extended to cover also this case. Example configuration targeted that could reproduce the problem: curl 7.87.1-DEV () libcurl/7.87.1-DEV .... OpenLDAP/2.6.3 Protocols: file ftp ftps http https ldap ldaps Closes #10445
