IIS 7.5 site using impersonation does not have permissions to access Sharepoint web services -

edit updated new information

i've been trying configure asp.net site utilize windows authentication impersonation, , utilize phone call sharepoint 2010 web services.

i've enabled impersonation , windows authentication on site, , given in "classic" .net 4.0 app pool identity. display user logged in. when site run server, works fine - user impersonated correctly. tried several user accounts (but local admins...). can upload file sharepoint records "created by" "modified by" site user (and not app pool identity). situation want.

when run client machine, fails. page loaded, seems fail when tries access sharepoint lists service 401 unauthorised. farther inquiries have shown me next info sharepoint weblogs when calling list.asmx service:

2012-01-12 22:42:52 10.197.104.208 post /iain/cesa/_vti_bin/lists.asmx - 80 - 10.143.16.141 mozilla/4.0+(compatible;+msie+6.0;+ms+web+services+client+protocol+4.0.30319.239) 401 0 0 13 2012-01-12 22:42:52 10.197.104.208 post /iain/cesa/_vti_bin/lists.asmx - 80 - 10.143.16.141 mozilla/4.0+(compatible;+msie+6.0;+ms+web+services+client+protocol+4.0.30319.239) 401 1 2148074254 3 2012-01-12 22:42:52 10.197.104.208 post /iain/cesa/_vti_bin/lists.asmx - 80 - 10.143.16.141 mozilla/4.0+(compatible;+msie+6.0;+ms+web+services+client+protocol+4.0.30319.239) 401 1 5 1

from: http://support.microsoft.com/kb/969060 know that: "the win32 status of "2148074254" (also defined -2146893042 / 0x8009030e / sec_e_no_credentials) means "no credentials available in security package." in other words, client has not sent credentials."

this looks web site not passing impersonated credentials sharepoint site. there way of solving this? because works server i'm sure can work, i'm @ wits end trying find solution.

this caused windows authentication using ntlm rather kerberos (i thought using kerberos...).

i'm looking getting kerberos configured, big task. in meatime have moved site , hosted on same sharepoint web front end end web services contacting. there double hop, no need deleaged credentials, , works :)

sharepoint-2010 permissions iis-7.5

How do I check if an insert was successful with MySQLdb in Python? - i have code: cursor = conn.cursor() cursor.execute(("insert new_files (videos_id, filename, " "is_processing) values (%s,%s,1)"), (id, filename)) logging.warn("%d", cursor.rowcount) if (cursor.rowcount == 1): logging.info("inserted values %d, %s", id, filename) else: logging.warn("failed insert values %d, %s", id, filename) cursor.close() fun is, cursor.rowcount always one, though updated database create videos_id unique key. is, insert fails because in tests same videos_id going appear (and when check database, nil inserted). whatever reason, rowcount 1 - logging.warn have spits out rowcount of 1. so, question: can utilize rowcount work out if insert went fine? if so, (presumably) doing wrong? otherwise, how check if insert went fine? your code not commit after modifications (your modifications rolled back). should...
