Changing default Samba user in Dolphin

For reasons too complicated to go into I run several accounts on my main desktop PC. Their home directories can then be connected to their equivalents on my other machines (eg my laptop). I do this via Network -> Samba Shares -> etc in Dolphin.

Setting up my brand new PC I tried to connect one of my accounts to my old PC and accidentally identified the wrong user name and password. So when I go to the Samba share it shows the wrong account’s home directory.

Silly, but it must be easy to fix this. So how do I do it? (I think it mus be in the wallet, but I can’t find any reference to this in the menu.)

I eventually solved it, though I suspect there is a better way.

KDE wallet is to be found in System Settings under “Account Details”. When I looked there I found it said it was storing one password. However, there didn’t seem to be any way to delete this one password (which is what I was looking for) but there is a way to delete the entire folder that contains the password entries. Since there was only the one password, it didn’t seem a drastic measure to choose what otherwise have been a nuclear option, so I deleted the folder.

I was then able to store the correct user name and password.
