in our custom schema we have used several attributes with the syntax:
attributetype ( myAttributeType:106 NAME ( 'casFileContent' )
DESC 'Contains the file'
We defined this schema before this syntax was dropped.
Everything worked for a long time. Now with OpenLDAP Version 2.4.39 and
newer a slapcat does no longer export this attributes as MimeContent, but
as plain text. So the ldif can't be used for importing. So I started a
research why and found that this syntax was dropped. But for downward
compatibility shouldn't it still export this syntax as mime content,
This would be important, since in inetorgperson.schema the 2 attributes
userSMIMECertificate and userPKCS12 still use it.
What syntax should I use for files stored in LDAP?
And even more important, how can I change the syntax of a attribute. Is
there a migration strategy to change the syntax of a attribute?
