Subject: [PATCH] Refresh manually acquired creds from client keytab
|
|
|
31ace6 |
|
|
|
31ace6 |
If a client keytab is present but credentials are acquired manually,
|
|
|
31ace6 |
the credentials would not be refreshed because no refresh_time config
|
|
|
31ace6 |
var is set in the cache. Change kg_cred_time_to_refresh() to attempt
|
|
|
31ace6 |
a refresh from the client keytab on any credentials which will expire
|
|
|
31ace6 |
in the next 30 seconds.
