Unix password replication to a set of computers

A method of replicating a UNIX password from a source computer to a delimited set of target computers performed by an application executing on a computer system, comprising:

• receiving an identity of a source computer;
• receiving identities of the target computers;
• reading an encrypted UNIX password associated with a user identity from the source computer;
• for each target computer, determining whether the user identity or another identity corresponding to the user identity, and a corresponding existing password, are included in a password file of the target computer, wherein the password file is an /etc/shadow file;
• looking up a UNIX password complexity requirement of the source computer;
• for each target computer, looking up a UNIX password complexity requirement of the target computer;
• for each target computer, comparing the UNIX password complexity requirement of the target computer to the UNIX password complexity requirement of the source computer;
• for each of the target computers whose UNIX password complexity requirement is not stronger than the UNIX password complexity requirement of the source computer, writing the encrypted UNIX password into a first entry associated to the user identity in the password file on the target computer;
• for each of the target computers whose UNIX password complexity requirement is stronger than the UNIX password complexity requirement of the source computer, rejecting writing of the encrypted UNIX password into the first entry associated to the user identity in the password file on the target computer;
• and
• for each of the target computers for which the user identity or another identity corresponding to the user identity is not stored in the password file, rejecting writing of the encrypted UNIX password to the target computer.
