Yet when I look at the RFC, I see:

   The following syntax definitions [RFC2252] are used by this schema.
   The nisNetgroupTripleSyntax represents NIS netgroup triples:

           ( nisSchema.0.0 NAME 'nisNetgroupTripleSyntax'
             DESC 'NIS netgroup triple' )

   Values in this syntax are represented by the following:

        nisnetgrouptriple = "(" hostname "," username "," domainname ")"
        hostname          = "" / "-" / keystring
        username          = "" / "-" / keystring
        domainname        = "" / "-" / keystring

   X.500 servers may use the following representation of the above
   syntax:

        nisNetgroupTripleSyntax ::= SEQUENCE {
         hostname  [0] IA5String OPTIONAL,
         username  [1] IA5String OPTIONAL,
         domainname  [2] IA5String OPTIONAL
        }


That looks like IA5 string to me.

I will note that OpenLDAP cannot handle the 1.3.6.1.1.1.0.0 SYNTAX, and 
reports this as an undefined attribute.
