Newbie: Attributes

[Paul Crittenden <crittend@storm.simpson.edu>]

I am new to ldap and I didn't set up this server. I need to add some 
attributes to classify users, such as faculty, students, staff etc. I 
understand that an attribute is supposed to exist in one of the schema 
files included in the slapd.conf file and userClass exists in 
cosine.schema. I set up a file like the following.

File to make changes contains:

dn: cn=pdc, dc=simpson, dc=edu
           changetype: modify
           add: userClass
           userClass: staff

I use the command ldapmodify -a -f ./entrymods
and I get the error:

ldap_sasl_interactive_bind_s: No such attribute

zI have spent 2 days looking at this and have read everything I can find as 
well as searched archives looking for the answer. It doesn't seem that it 
should be that difficult but I am stumped. Any help would be appreciated.
