Subject: [PATCH 17/19] PAC: allow to disable UPN check
|
|
|
0034f4 |
|
|
|
0034f4 |
Currently it was not possible to skip the UPN check which checks if the
|
|
|
0034f4 |
UPN in the PAC and the one stored in SSSD's cache are different.
|
|
|
0034f4 |
Additionally the related debug message will show both principals if they
|
|
|
0034f4 |
differ.

Resolves: https://github.com/SSSD/sssd/issues/6451
