From 2d2c67e3ed30e7d9850447826b2cc968f28ae681 Mon Sep 17 00:00:00 2001 From: Steve Holme Date: Sun, 3 Apr 2016 11:15:03 +0100 Subject: krb5: Only generate a SPN when its not known Prior to this change, we were generating the SPN in the SSPI code when the credentials were NULL and in the GSS-API code when the context was empty. It is better to decouple the SPN generation from these checks and only generate it when the SPN itself is NULL. This also brings this part of the Kerberos 5 code in line with the Negotiate code. --- lib/vauth/krb5_sspi.c | 12 +++++++----- 1 file changed, 7 insertions(+), 5 deletions(-) (limited to 'lib/vauth/krb5_sspi.c') diff --git a/lib/vauth/krb5_sspi.c b/lib/vauth/krb5_sspi.c index 6afd83dde..da08f8f03 100644 --- a/lib/vauth/krb5_sspi.c +++ b/lib/vauth/krb5_sspi.c @@ -85,6 +85,13 @@ CURLcode Curl_auth_create_gssapi_user_message(struct SessionHandle *data, unsigned long attrs; TimeStamp expiry; /* For Windows 9x compatibility of SSPI calls */ + if(!krb5->spn) { + /* Generate our SPN */ + krb5->spn = Curl_auth_build_spn(service, host); + if(!krb5->spn) + return CURLE_OUT_OF_MEMORY; + } + if(!krb5->credentials) { /* Query the security package for Kerberos */ status = s_pSecFn->QuerySecurityPackageInfo((TCHAR *) @@ -104,11 +111,6 @@ CURLcode Curl_auth_create_gssapi_user_message(struct SessionHandle *data, if(!krb5->output_token) return CURLE_OUT_OF_MEMORY; - /* Generate our SPN */ - krb5->spn = Curl_auth_build_spn(service, host); - if(!krb5->spn) - return CURLE_OUT_OF_MEMORY; - if(userp && *userp) { /* Populate our identity structure */ result = Curl_create_sspi_identity(userp, passwdp, &krb5->identity); -- cgit v1.2.3
