The gadspwsync script allows for the synchronization of Google passwords with eDirectory passwords using the free Google Apps Directory Sync tool from Google. It is a one-way sync from eDirectory to Google allowing existing eDirectory password policies to be applied to Google passwords.
Google Apps Directory Sync can only read passwords from LDAP if they are stored as SHA1 or MD5 hashes or as Plaintext. Other password formats are not compatible. The basis of the script is to retrieve a user’s password from eDirectory using Universal Password and the Getpass Cool Tool as a SHA1 hash and write it back to eDirectory to an unused attribute.
gadspwsync.pdf contains detailed instructions about implementing the script or you can link to the article here.
