It appears that the database of my client is not accessible. They can provide me an excel file with the members.

The intended application actually is an election. It is a one time thing. Every member is using this application once, and presumably not all of them. Would it still be unwise then to put these 25000 accounts in an ordinary acl_users folder?

You could import the users in a database (like mysql) and authenticate with a PAS plugin. Performance wise it could be really slow to have 25K users in a userfolder.

I found this userfolder today as well : http://www.simplistix.co.uk/software/zope/simpleuserfolder. You could easily write a ZSQL method for authentication for this (it's easier than writing a PAS plugin). If you have time or resources to write a PAS plugin I suggest to invest some time for that.

Martijn.
