Subject: [PATCH] Properly initialize ccaches before storing into them
|
|
|
c530df |
|
|
|
c530df |
krb5_cc_new_unique() doesn't initialize ccaches, which results in the
|
|
|
c530df |
krb5 libraries being aware of their presence within the collection but
|
|
|
c530df |
being unable to manipulate them.
|
|
|
c530df |
|
|
|
c530df |
This is transparent to most gssproxy consumers because we just
|
|
|
c530df |
re-fetch the ccache on error.
