However, in the DSPUSRPRF, I see that there is another parameter "UPPWEI," which can be set to either a value of "-1" or "0". Do either the "0" or "-1" override the default of 60 days?
Also, what do "0" and "-1" mean? Do both intervals mean that the password never expires for the user profile?
The UPPWEI field corresponds to the password expiration interval field. The values of "0" and "-1" are internal representations for the values of *SYSVAL and *NOMAX respectively.
In other words, when you see "0" that means that the password expiration interval for that profile is set to *SYSVAL. When you see "-1", it means that the interval is set to *NOMAX
