This allows user commands to be authenticated via passwords.

To enable In ecflow 5 this functionality is enabled by default, however, in ecflow 4 this must have been built with -DENABLE_SECURE_USER. To check this is the case, please invoke:

ecflow_client --version  # the output should include *secure_user*
ecflow_server --version  # the output should include *secure_user*

One password file each, must be be specified for the client and server. In both cases, the file is located via ECF_PASSWD environment variable.

The default internal name of the password file is ecf.passwd, hence the server will by default look for the password of name <host>.<port>.ecf.passwd.

The format of the file is the same for both client and server. 

4.5.0  # this is the version number
# comment
# <user> <host> <port> <passwd>
fred machine1 31423141 xydd5j
fred machine2 31423141 xydd5j
fred machine3 31423141 xydd5jggg

This format allows the same  same file to be used for multiple servers.

user1 machine1 3141 sdfrg
user2 machine1 3141 ssdft
user3fred  machine1 3141 ggsdsd

The password file for the server must contain at least one user that matches the host and port of the server, otherwise and , an error is issued, and the server can not be started.

If ECF_PASSWD environment variable is specified, then the file is read by the client and server.

Then every Every client user command , sends the password to the server. The server will then compare the password for the user with its own file. If it matches, the command is authenticated, otherwise, the command fails. 

If the password is set on the server, but not on a client, then that user will be denied all access.

The password file can be reloaded to add/remove users. However, only users who appear in the password file , can do this.
