Re: [vchkpw] poppasswd backwards compatibility
I resolved this issue: the hashed password in /var/qmail/user/poppasswd is compatible with the hashed password in /etc/passwd. A custom script will convert the users in /var/qmail/user/poppasswd to /etc/passwd format. The vconvert -e -m is used to convert that /etc/passwd file into mysql users. I ran a number of tests with this technique and converted users authenticated just fine with pop3, squirrellmail and sqwebmail. Only item missing from the database is the clear text password, but that is acceptable.

No. You can't convert crypted passwords back to plain text ones. I would like to simply migrate the data in poppasswd to the vpopmail mysql database. I've managed it to keep the encrypted passwords in an old vpopmail password cdb file and let vpopmail add the encrypted password to the cdb file by compiling vpopmail with '--enable-learn-passwords=y' switch in configure. This requires your users to login once _NOT_ using CRAM-MD5, for vchkpw being able to successfully authenticate and write the received clear test password to database. I don't know if this works with a MySQL backend for user management too, I've only tested it with cdb files. HTH -- Peter

Re: [vchkpw] poppasswd backwards compatibility
Hi Peter, I was able to move existing user's passwords into an /etc/password file and use vconvert -e -m to move them to the mysql vpopmail database and it's password format. Would your suggestion below enable me to skip the conversion to /etc/passwd and move these users and there old style passwords directly into mysql vpopmail? Thanks for your help.

[vchkpw] poppasswd backwards compatibility
My users are are stored in the /var/qmail/user/poppasswd style database. This is using crypted passwords generated similarily to the script on Paul Gregg's site below: http://www.pgregg.com/projects/qmail/mkpasswd.php These passwords do not appear compatible with the md5 crypted passwords used with vpopmail and mysql.

I would like to simply migrate the data in poppasswd to the vpopmail mysql database. I did try to replace the password in the vpopmail database with password in poppasswd, but that obviously didn't work. Thanks, Joe CedarNet LLC

Thanks Peter. A question still remains. Is there anyway to tell vpopmail to not use MD5 and use the older crypt'd format?
