I have an older ldap, 2.3.27, and I recently added a new ldap attribute called gpcmailxfergroup. Here is the schema line:
attributetype ( 1.3.6.1.4.1.17432.1.20 NAME 'gpcmailxfergroup' DESC 'which group a mail id is in for the mail xfer' EQUALITY caseIgnoreMatch SUBSTR caseIgnoreSubstringsMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.15 SINGLE-VALUE )
and I added it to the objectclass for us (called gpcentry) as I have added a number before. When I do a slapcat, I get:
UNKNOWN attributeDescription "GPCMAILXFERGROUP" inserted.
I apologize if this should be posted at umich ldap group, but I was not sure if this might be an openldap issue. If I am wrong, I will be glad to repost. Thanks!
