Remote Web Password modification for Svn in Linux

Linux Remote Password Change Tool

Usage:
1. Place the changepasswd. cgi and changepasswd. ini files in the cgi-bin directory under the Apche installation directory.
2. Check the position of the prel tool (My :#! /Usr/bin/perl-W)
/Usr/bin/perl
3. Change changepasswd. cgi 84th to the path where htpasswd is located (My:/project/Apache/bin/htpasswd)
4. Modify the INI file of changepasswd. cgi 128 to the full path (My:/project/Apache/cgi-bin/changepasswd. INI)
5. configuration file changepasswd. ini line 2nd authuserfile = Password Storage path (My:/svndata/SVN-auth-file/passwd)
6. configuration file changepasswd. ini 3rd logfile = operation log storage path (My:/project/Apache/cgi-bin/changpasswd. Log)

Note:
1. Do not use the-M parameter when using htpasswd. If it was previously used, you can re-enter it for update.
2. changpasswd. log must have the "w" Write Permission

 

Copy the following content and save the file changepasswd. ini with the INI suffix.

[Path]
Authuserfile =/Repository/auth/AuthFile
Logfile =/Repository/auth/changpasswd. Log
[Setup]
Pwdminlen = 6
[HTML]
Title = SVN User Password self-help Modification
Description = SVN User Password self-help Modification
Yourname = User Name
Oldpwd = old password
Newpwd1 = New Password
Newpwd2 = confirm new password
Btn_change = Modify
Btn_reset = Reset

Changepwdok = Password Changed successfully
Changepwdfailed = An error occurred while changing the password.
Servererror = Server Error
Passmustgreater = the number of new passwords must be greater
Twopassnotmatched = the two passwords are inconsistent.
Entername = enter the user name
Enterpwd = PASSWORD not entered
Errorpwd = Your password is incorrect
Back = return

 

Copy the following content and save the file changepasswd. cgi with the CGI suffix.

After completing the steps 1-6, you can modify the user's password through the remote web.
