Hi I'm using a python function as follows for fetching kerberos tokens
Any idea regrading the reason for delay?
-I have tried using IP address as well as the FQDN as the argument of the main funtion. all same.
-ping from all my machines to the server takes same time.
My environment:
Python 3.5.2
Ubuntu 16.04

Hi I'm using a python function as follows for fetching kerberos tokens
def get_token(server): service = gssapi.Name("HTTP@%s" % server, gssapi.NameType.hostbased_service) ctx = gssapi.SecurityContext(name=service, usage="initiate") attempts = 0 while True: try: print("before") token = ctx.step() print("after") break except Exception as e: attempts += 1 print(attempts) if attempts < MAX_TOKEN_ATTEMPTS: logger.debug("exception while getting Kerberos token, trying again", exc_info=e) else: raise OSError("too many failures while getting Kerberos token, discarding request") from e b64token = base64.b64encode(token) return b64tokenThe function is giving expected result. However the problem is, in one of my machine, the step "token = ctx.step()" is taking more than 5 sec to complete. In my other other machines it's taking less than 2 sec.
