We are testing NIS to LDAP data migration.
Is the nisMailAlias schema available in Symantec/CA Directory ?
Release : 14.x
nisMailAlias is not available in Symantec/CA Directory schema.
Symantec/CA Directory supports RFC2307: https://datatracker.ietf.org/doc/html/rfc2307 ("An Approach for Using LDAP as a Network Information Service").
nisMailAlias is not defined in the above RFC. There are a few places on the Internet where nisMailAlias is mentioned, but there is no reference to any official document (RFC) which defines it.
It looks like nisMailAlias is some extension that may be supported by some LDAP/X.500 vendors, but is not a part of any standard.
Symantec Directory schema can be extended to include custom attributes and/or classes, including nisMailAlias
See Directory documentation for the information on schemas: https://techdocs.broadcom.com/us/en/symantec-security-software/identity-security/directory/14-1/ca-directory-concepts/directory-schemas.html
