Which driver?

I _think_ the SQL driver encrypts by default with the php md5()  
function, which
I always hear isn't compatible with the MySQL md5() function for some
reason.  But that is hear-say...

I'm not sure the CUSTOMSQL driver encrypts it at all?

So, the question would seem to be what format of encryption do you use
in your Database?  If it isn't plain text, and isn't compatible with
php's md5() function, then you likely are out of luck.

If you don't set this, it uses the Horde login password.  If you
do set this, it forces the user to input the password to forwards and
uses that.  Or at least that is how I remember it working.

> From Horde? I am quite confused. Authentication in Horde is done by IMP.

So the Horde/IMP password is used if $conf['enabled']['authenticate'] is
false, and the user's input is used if it is instead set to true, IIRC.

I don't think you can.  I think it only uses php's md5() right now.
So the only way to change that would be to change the code, I _think_.

What value to you use with passwd?  If it isn't md5-hex, then forwards
probably won't work. (I think the php md5() function is what passwd calls
md5-hex).

No, I think no one ever ported over any additional encryption methods to
forwards sql drivers like we did for passwd, so if you're not using
php md5() (aka md5-hex) encryption, or plain text, then I think it just
doesn't work.

I'm no expert on any of this, even though I originated the programs.
I've not used them for a while, as I've switched to Ingo instead actually.
But if my memory serves, you are out of luck, and the only options are:

1) File an enhancement bug ticket and hope someone does it.
2) Sponsor a bounty for what you need, and hope someone does it.
3) Write the code yourself (basically steal it from passwd).
4) Change your SQL passwords to another format (probably not feasible).
