CRITICAL: 613 VAS method cannot be loaded, /usr/lib/security/methods.cfg invalid

Ensure the structure of the file is correct. An example methods.cfg from AIX 6.1 is attached (after QAS has been installed.)

1- Module names for example "VAS:" must have no leading space precedding their name
2- Modules can be commented out by using a asterix (*) - hashes must not be used (#)
3- Ensure tabs and carriage returns are in the correct place
