Duplicate declaration

[rvalkenaers]

Hello,

I'm trying to add the ssh-keys to the ldap schema (and it's working).

However the second time I run puppet I get a duplicate error:
Error details:
Execution of '/usr/bin/ldapadd -H ldapi:/// -d 0 -f /tmp/ldap_apply_work20150805-8865-1y0lqic -QY EXTERNAL' returned 80: ldap_add: Other (e.g., implementation specific) error (80)
additional info: olcAttributeTypes: Duplicate attributeType: "1.3.6.1.4.1.24552.500.1.1.1.13"
adding new entry "cn=openssh-openldap,cn=schema,cn=config"
Error: /Stage[main]/Ldap::Server/Ldapdn[schema add ssh]/ensure: change from absent to present failed: Ldap Modify Error

My declaration looks like this:

ldapdn{'schema add ssh':
dn => "cn=openssh-openldap,cn=schema,cn=config",
attributes => ["objectClass: olcSchemaConfig",
"cn: openssh-openldap",
"olcAttributeTypes: {0}( 1.3.6.1.4.1.24552.500.1.1.1.13 NAME 'sshPublicKey' DESC 'MANDATORY: OpenSSH Public key' EQUALITY octetStringMatch SYNTAX 1.3.6.1.4.1.1466.115.121.1.40 )",
"olcObjectClasses: {0}( 1.3.6.1.4.1.24552.500.1.1.2.0 NAME 'ldapPublicKey' DESC 'MANDATORY: OpenSSH LPK objectclass' SUP top AUXILIARY MUST ( sshPublicKey $ uid ) )"],
unique_attributes => ['olcAttributeTypes'],
ensure => present,
}

I already tried a ton of things as unique_attributes but nothing seems to work.

Am I missing something?

Any help is appreciated.
