mail is a CASE IGNORE string. I,E, Case changes do not make the strings different.

When trying to add new value towards the mail attribute, which is essentially the same address just with different cases, it is prevented.

I created an user like this:

dn: uid=patrick,ou=people,dc=example,dc=org
objectClass: inetOrgPerson
objectClass: posixAccount
objectClass: shadowAccount
uid: patrick
sn: User
givenName: patrick
cn: patrick
displayName: Patrick
uidNumber: 10001
gidNumber: 5000
userPassword: {SHA}[NOPE]
gecos: Patrick
loginShell: /bin/bash
homeDirectory: /home/patrick

mail: example@googlemail.com

Then I wanted to add another mail with different casing, because according to RFC 5321 those two could be different email addresses:

dn: uid=patrick,ou=people,dc=example,dc=org
changetype: modify
add: mail
mail: Example@googlemail.com

However this fails with

ldap_modify: Type or value exists (20)
additional info: modify/add: mail: value #0 already exists

While doing the same with

dn: uid=patrick,ou=people,dc=example,dc=org
changetype: modify
add: mail
mail: Example123@googlemail.com

It works fine.

Any idea how to solve this?
