RE: Cannot change user passwords
Hello Edrees,
You can login to Dynamics GP as 'sa' and in the User Setup window, change that user's password for them.
When you're attempting to mark the 'Change Password Next Login' option, are you referring to the User Setup window in Dynamics GP? If so, are you logged on as 'sa' or 'DYNSA' when doing so?
In regards to the 'Enforce Password Policy' options, those settings are actually enforced by SQL Server working with Active Directory, there isn't any real settings in Dynamics GP for that, other than we allow you to also use those policies with the GP logins to go along with the Windows AD accounts.
I'd be curious if you login to the SQL Server Mgmt Studio, then under Security > Logins, right-click on any GP login (not sa) and go into Properties. On the 'General' page of the login's Properties window, do you have the option to mark 'Enforce Password Policy' or is it disabled here as well?
If disabled in SQL as well, even when using the 'sa' login, then there is something not setup correctly either on the SQL or Active Directory side. In prior versions of Dynamics GP, we used to require certain versions of SQL, but with Dynamics GP 2015 you should be ok with that, so I would also maybe check your SQL Native Client driver being used for the ODBC DSN connections with Dynamics GP.
Thanks
