(ITS#7773) slapo-constraint falsely restricts modrdn with count 1

Full_Name: Version: 2.4.38 OS: URL: Submission from: (NULL) (212.227.35.93)

Sometimes it's useful to restrict an existing attribute type declared multi-valued to a single value with slapo-constraint to avoid modifying the standard schema.

Example:

constraint_attribute uid count 1 restrict="ldap:///ou=example??sub?(objectClass=account)"

Unfortunately when using uid in the RDN one cannot rename the entry anymore even when deleteoldrdn is set to true.

slapo-constraint should handle this case exactly like SINGLE-VALUE RDN attributes are handled.
