While reading the different components of the HBAC rules failover
|
|
|
ef0222 |
handling was missing. Since the access control is typically the second
|
|
|
ef0222 |
step after authentication SSSD would have already switched to a working
|
|
|
ef0222 |
server or into offline mode during authentication. But if e.g. ssh keys
|
|
|
ef0222 |
are used for authentication and user data are read from cache the HABC
|
|
|
ef0222 |
rule searches might have to handle failover as well.
