Hi,

I have configured FBA on sharepoint 2019 ( on prem )

Problem:
Form based authentioncation not working, I mean ,user cannot login to portal
though I hve given site collection administration permission.

Solution Required:
Please let me know , how can user login using FBA, as keeps asking credentials,i have rechecked credential its totally fine,

and how can give password rest option to user to let him chnage password himself
Note: windows authentication is working fine, only problem in F

Used this reference :
