Re: [vchkpw] Massive Folders
There are a few different ways to do it depending on your backend, if
you are using MySQL, then you can just update the mysql database with
the user and password, leaving the maildir directory blank and it will
automatically be updated when you pop into the account or sendmail to
the account (really fast for creating 10K+ users). If you are using the
cdb interface, then you will have to create the users using the vpopmail
tools, which might take 5-15 minutes depending on the number of users,
disk speeds, CPU etc.
I have just written a script that would do a mysql update query to
md5('password'); into the mysql database. However the problem appears to
be that the passwords set by the vpasswd utility dont appear to be md5
in the same way that the mysql query with md5() function works?
Is that correct?

Hi,
Yes, that is correct. How are you running this script ? Is it a perl
or php program ?
You can create the correct md5 password in perl or php and then update
the database with it.

It appears as though the passwords all start with a $1 how do we go
about creating the right md5sums for example with php? I keep getting
b.s. information created and it will fail authentication.
p.s. thanks for all the help. I really appreciate it.

Hi,
$encpass = crypt('password','$1$salthere$');

Re: [vchkpw] Massive Folders
Hi,
$encpass = crypt('password','$1$salthere$');
Where does vpopmail keep the salt or how does that work in regards to
the vpasswd utility etc?

Hi,
Vpopmail uses $1$ + random letters for the salt. The actual salt is not
kept anywhere.
#ifdef MD5_PASSWORDS
salt[0] = '$';
salt[1] = '1';
salt[2] = '$';
salt[3] = randltr();
salt[4] = randltr();
salt[5] = randltr();
salt[6] = randltr();
salt[7] = randltr();
salt[8] = randltr();
salt[9] = randltr();
salt[10] = randltr();
salt[11] = 0;
#else
salt[0] = randltr();
salt[1] = randltr();
salt[2] = 0;
#endif
tmpstr = crypt(clearpass,salt);

[vchkpw] Massive Folders
Hello, I am managing a group of servers that is running Redhat Enterprise Linux v3. The Issue that I have just discovered is that we have now over 32000 users. Thats causing a problem as ext3 file system does not support more than 32000 folders in any one particular folder. Is there any way to setup vpopmail so that it supports directory hashes or anything similar to that. Does anyone have any solutions to resolve this type of issue. Regards, Jimmy.
