When using the NOEXEC option in the sudoers file with the Sudo package available in the AIX Toolbox, the following error message is received...
$ sudo id
exec(): 0509-036 Cannot load program id because of the following errors:
0509-150 Dependent module /opt/freeware/libexec/sudo_noexec.so could not be loaded.
0509-022 Cannot load module /opt/freeware/libexec/sudo_noexec.so.
0509-026 System error: A file or directory in the path name does not exist.
It appears that none of the Sudo RPMs that are currently posted have the sudo_noexec.so library included in them.
