When configuring refint on slapd 2.4.49 the following is accepted :
dn: olcOverlay={2}refint,olcDatabase={1}mdb,cn=config
objectClass: olcOverlayConfig
objectClass: olcRefintConfig
olcOverlay: {2}refint
olcRefintAttribute: seeAlso
olcRefintNothing: cn=admin,dc=test
but
olcRefintNothing: cn=admin space,dc=test
is rejected when I ldapadd the configuration with the message :
ldap_add: Constraint violation (19)
additional info: <olcRefintNothing> extra cruft after <string>
I tried various quoting :
cn="admin space",dc=test
cn=admin\20space
"cn=admin space"
