Hi,
Thanks to both responders. The final working version of local.schema now looks like this:
attributeType ( 1.3.6.1.4.1.22280.1021.3.1 NAME 'x-sdids-passwordExpirationTime' DESC 'TELUS defined password policy attribute type used by enPortal.' EQUALITY generalizedTimeMatch ORDERING generalizedTimeOrderingMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.24 SINGLE-VALUE USAGE userApplications )
objectclass ( 1.3.6.1.4.1.22280.1021.4.1 NAME 'x-sdids-enPortal' DESC 'Indicates that this entry has additional attributes used by enPortal.' AUXILIARY MAY x-sdids-passwordExpirationTime )
After restarting slapd, and adding the 'x-sdids-enPortal' objectClass to an existing entry, I was able to add a 'x-sdids-passwordExpirationTime' attribute value. Nice.
Thanks, Bryce Powell
