The thing is I want to avoid using scripts or an external binary (which would be possible) for performance reasons. I think the internal passwd file handling from dovecot would be best. It should be pretty easy to do a patched version where only the fields are replaced by the ones my passwd files use. -- Regards, Stephan

So a short solution would be a patch to dovecot. A more general solution could be a separate scheme beside the existing auth backends http://wiki2.dovecot.org/PasswordDatabase or a mechanism to specify passwd fields as you suggested. Andreas

The setup is complex and lots of other software parts depend on the passwd file. Since they should all be interacting it is no good idea to spread the same data over several "databases". Furthermore we are not talking about _one_ passwd-like file but thousands (one for every domain). Believe me, I thought about it before asking exactly this question and not for some solution. If there is no chance to convince Timo for something like a passwd-scheme parameter useful for more people than just me I will probably rewrite the stuff myself. Nevertheless if someone kindly points me to the right piece of code I could save some hours searching for it myself... -- Regards, Stephan

[Dovecot] How to bring dovecot to using a slightly modified passwd file
Hello all, I am trying to use a setup where domains have separate passwd files with a slightly different layout. Is there a way to tell dovecot that a passwd file contains everything it looks for but on different positions inside the passwd file line? Standard passwd: USERNAME:PASSWD:UID:GID:HOME:extras different layout: USERNAME:PASSWD:extras:UID:GID:HOME Or do I have to patch the source, and where if necessary? Thanks for your help. -- Regards, Stephan
