kadmin.local getprincs command results in passing '*' as a principal to
KDB driver function that looks up the principals.
The whole filter looks like this
(&(|
(objectclass=krbprincipalaux)
(objectclass=krbprincipal)
(objectclass=ipakrbprincipal))
(|(ipakrbprincipalalias=*)
(krbprincipalname:caseIgnoreIA5Match:=*)))
There are two parts of the LDAP filter we use to look up principals, the
part with 'krbprincipalname' uses extensible filter syntax of RFC 4515
section 3:
extensible = ( attr [dnattrs]
[matchingrule] COLON EQUALS assertionvalue )
/ ( [dnattrs]
matchingrule COLON EQUALS assertionvalue )
In case we've got a principal name as '*' we have to follow RFC 4515
section 3 and reencode it using <valueencoding> rule from RFC 4511
section 4.1.6 but only to the part of the filter that does use assertion
value.
