Random Login/Passwords not working with iMIS Membership Web Service

We have a client who upgraded from 10.6 to 15.1.1 back in September. They also went from using the e-Series login to the iMIS Membership Web Services on their website. The problem they are encountering is that random member login/passwords are not working, nor will the Password reset work for those users. This isn't happening for all members however. If a staff member changes a member's password within iMIS, they then are able to login on the website via the web service with no problem. We have verified that all IDs exist in Name_Security, Name_Security_Groups, & Name_Fin.

The Event Viewer on the App Server is returning "Membership credential verification failed." for those users who can't login.

Anyone else encountering this? Is there a solution?

We're also having this

We're also having this issue, we will set their password on a back office IMIS and when they try to login an error message: "User Unknown Error Provider". Any idea what could it be?..

Thank you,

I tried resyn net contacts and that didn't fix it for us.


Same problem

Hi guys,

We are having the same problem.  Some users can't login, and when they try to reset their password they get "Error: Login Error".  This creates an event in the app server saying "Membership credential verification failed".  We created the users in 10.6 using the eSeries tool, then upgraded to 15.1.3.

We've put through an SMR to ASI but if you have been able to fix this can you post the solution here for future reference?

Thanks guys,


Sync NetContacts

We were able to resolve this by running the "Sync NetContacts" option the DBRepair utility.
