Hi, following search shows correct results: ldapsearch -Y EXTERNAL -H ldapi:/// \ -b "cn=billy kid,ou=tombstone,o=avci,c=de" -s base \ "(l:caseExactmatch:=Tombstone)" sn l

# LDAPv3 # base <cn=billy kid,ou=tombstone,o=avci,c=de> with scope baseObject # filter: (l:caseExactmatch:=Tombstone) # requesting: sn l #

# Billy Kid, tombstone, avci, de dn: cn=Billy Kid,ou=tombstone,o=avci,c=de sn: Kid l: Tombstone

# search result

# numResponses: 2 # numEntries: 1

changing the filter to (l:caseExactmatch:=tombstone) shows the expected results

# search result search: 2 result: 0 Success

Now a search with assertion control allways shows error 122

ldapsearch -YEXTERNAL -e assert='l=Tombstone'-H ldapi:/// -b "cn=Billy Kid,ou=tombstone,o=avci,c=de" -s base sn l

LDAPv3 # base <cn=Billy Kid,ou=tombstone,o=avci,c=de> with scope baseObject # filter: (objectclass=*) # requesting: ldapi:/// sn l #

# search result search: 2 result: 122 Assertion Failed

The same applies to an extended assertion filter ldapsearch -YEXTERNAL -e assert='l:caseExactmatch:=Tombstone' -H ldapi:/// -b "cn=Billy Kid,ou=tombstone,o=avci,c=de" -s base sn l

# search result search: 2 result: 122 Assertion Failed

What is wrong with this assertion filter?
