sync-accounts-createuser - helper/hook program for sync-accounts
sync-accounts-createuser is invoked by sync-accounts when sync-accounts
is creating a local account.
It must perform all of the tasks involved with local account creation
except for the actual changes to the password, shadow and group
At the very minimum, it must create the new account’s home directory
(with appropriate permissions). The supplied sync-accounts-createuser
script does exactly that.
It may also suggest to sync-accounts modifications to the new account’s
When sync-accounts-createuser is invoked, the passwd and group entries
will not yet have been set up, so it may not rely on them. sync-
accounts-createuser will not be supplied with any arguments. However,
the following environment variables will be set, giving details about
the account to be created:
sync-accounts-createuser should usually produce no output.
It can inhibit the creation of the user by outputting a single line not
containing a colon; in this case, a diagnostic message will be written
to sync-accounts’s logfile, and the user will be skipped.
Alternatively, it may write out an alternative password file entry, in
which case sync-accounts will use the supplied data for the local
passwd file instead of that from the remote host. The line should be
in Sys-V passwd file format (regardless of localformat or remoteformat
settings). The username field should be taken from
SYNCUSER_CREATE_USER, and the password field should be x.
0 All went well, or we wrote a line without a colon to say that
the account should not be created.
There were serious problems and sync-accounts should bomb out
The supplied sync-accounts-createuser does not check that it was not
supplied with any arguments; nor does it check that the
SYNCUSER_CREATE_* variables are set, or have sensible values.
