Yes, case-sensitive matching is an issue and I already saw that text in your drafts. I've simply added additional local constraints to the config limiting e.g. attribute 'uid' to lower-case values. So it was not that important to me. > Also, another requirement was to fix the schema so > that duplicate alias names could be easily detected and prevented (1.2). Are you talking about this text? https://tools.ietf.org/html/draft-bannister-dbis-mapping-00#section-1.2 Frankly I don't get it (besides the SHALL for LDAP client configuration). > Legacy unices ... depends how old we're talking.

I don't care about full NIS feature set. I've replaced it with something different. ;-) Ciao, Michael.
