multiple password hash algorithm in password row

[Beleggrodion]

I currently use Nextcloud 30.0.5 and miss the feature for multiple password hashes.

We had an internal application with a mariadb backend which provides all users for the local mailserver. Because i'm not happy with the external_user plugin (only login with email, no multi domain support,e tc.) a want to try this, but this is also not usable at the moment for me. Our database works with multiple password algorthm and i only can set here one algorithm.

All new accounts had an argon2id hash in the password row like: {ARGON2ID}$argon2id$v=Z$m=YYYYYY,t=X,p=1$XYZABC.....
Older accounts had the following: {HMAC-MD5}a321654.....
And other old accounts had something like: {MD5-CRYPT}$1$ASDDXSZi$X2.....

We implemented this that not all users are forced to change there password when we do some changes at the algorythm.
