The default sudo binary in 11.4 was changed from 32-bit to 64-bit, so the provided 32-bit libvas_sudo.so cannot be loaded.
 

The OS is 64 bit but the SAS package that was installed was 32 bit or the SAS package was 32 bit and then upgraded to a Solaris 11.4 supported version. 

RESOLUTION:

Upgrade to Safeguard Authentication Services version 4.2.3 or higher

After upgrading run the following commands:

/opt/quest/bin/vastool unconfigure sudo

/opt/quest/bin/vastool configure sudo

If the system is already at version 4.2.3 or higher just run the above to commands to resolve.
