Subject: [PATCH] Allow clock skew in krb5 gss_context_time()
|
|
|
963210 |
|
|
|
963210 |
Commit b496ce4095133536e0ace36b74130e4b9ecb5e11 (ticket #8268) adds
|
|
|
963210 |
the clock skew to krb5 acceptor context lifetimes for
|
|
|
963210 |
gss_accept_sec_context() and gss_inquire_context(), but not for
|
|
|
963210 |
gss_context_time(). Add the clock skew in gss_context_time() as well.
