easier migrating password_format to another

[moo]

it would be nice if i can change password_file format gracefully, without hurting existing users. switching to another format should still support the old one, and should update the file as soon as the user login (password learning)

I'm not likely to work on this anytime soon, but if you'd like to provide a patch I'll consider it.

I'm closing this ticket due to a lack of activity. The new chained password stores can alleviate this problem by allowing multiple password stores to be used. It won't do the migration, however.

If you have a patch against 0.11​ for this feature, please attach it and reopen the ticket.

Not knowing about this old ticket I just stumbled over it.

If you still care, the migration is now supported by setting multiple password stores and the AcctMgr option refresh_passwd = true. But it has not been back-ported to 0.10 branch so far.

I needed this, so I took care of it on my own. Any feedback is still welcome.

history of implementation:

• [10244] introduced the core function to 'trunk'
• [10250] added db storage support to prevent repeated refresh attempts for the same user
• [10286] added support for enabling/disabling the function from configuration admin page
• [10393] made the feature available as part of acct_mgr-0.3
• [10469] added the ability to restart the refresh for all users as often as needed
• [10470] finally made the full feature set available as part of acct_mgr-0.3.1

Have fun.
