enable pam user auth enables PAM user authentication support:
sp_configure "enable pam user auth", 0 | 1 | 2
where:
0 – disables PAM authentication. This is the default.
1 – indicates Adaptive Server first attempts PAM authentication, and then uses syslogins authentication if PAM authentication fails.
2 – indicates only PAM authentication may be used.
When PAM is enabled, password management is delegated to the PAM service providers.
