Descrizione
AIX 7.1 / 7.2 with SAS 5.1.1.4200 vasd dispatcher process segfaults causing auth failures.
SAS 5.1.1.4200
AIX 7.1 and 7.2
User authentications may fail with the following in syslog:
su example:
su: BAD SU from root to <username> at /dev/pts/0
ssh example:
sshd: Failed keyboard-interactive/pam for invalid user <username>
sshd: PAM: Authentication failed for illegal user <username>
At the same time, it can be seen that vasd dispatcher process is failing:
daemon: GenericIPCChild: Reparented to init; dispatcher must have died, shutting down and cleaning up socket file
Subsequent login attempts from a new session are successful. -
Causa
The dispatcher dying is triggered by occasional tokenGroup timeouts which impacts setting the timestamp in the user memory cache.
Product Defect ID: 422720 -
Risoluzione
Workaround: Subsequent logins from a new session are successful.
Product Defect ID: 422720 is a high-priority fix and is expected to be in the next release of Safeguard Authentication Services, version 5.1.2.
Version 5.1.2 is expected to be released in August 2023. -
