AdiIRC

The use-case here is to not be required to adjust different things like access lists from bots which recognize you based on your nick!ident@host mask when using AdiIRC while having a different SASL username/account. Also, people might simply like to use an ident which is different from their SASL username.

mIRC for example does not have this issue, there it is done like this: whatever value you put in as the ident in the Identd settings is used as the ident in the USER command during login into IRC, even if Identd server is enabled or not, no matter if you use SASL authentication or not. The password field for SASL in mIRC takes the syntax "username:password", which effectively makes it so its only used for SASL.

On Android, the Revolution IRC client also has separate fields for this and so is not an issue there either.

About Serverlist being crowded, how about having a separate SASL tab instead? This would create space in the General tab and then Ident could be added to the General tab after all, as I feel like that is where it belongs. I also feel like a non empty-value should override the Identd's value instead of the Username value.

Using my MS Paint skills I have made some changes to a screenshot, of what a slightly revised General tab could look like and have attached it.

Side-note: While editing this screenshot I have also realized now that it is not possible to set different server passwords (/PASS) for each individual server in a network, but only one global server password in the General tab for all servers in the network in the Servers tab. But that is another issue/feature request.

As you can see in the screenshot, there are now two separate "username" fields, the first one acts as "ident nick", the second one is only for sasl/scram/challenge auth logins.

Additionally when there is no login username present, it supports username:password in the password field for sasl/scram/challenge auth logins.

There is also a new option in Options -> Server -> "Use username as ident nick", this option is now on by default and all identd requests matching a connection will reply with the server "Username" field set in the Serverlist, if for some reason there is no match, it uses the default "ident Nick".

It will be in the next beta, but I am not sure when that is gonna be, so I made this build you can test https://adiirc.com/build/1565867850/AdiIRC.exe, you can run that as is in a folder somewhere or replace your current AdiIRC.exe with this one.

Let me know if there are any problems.
