Due to the fact that ldap read and write operations should be optionally done on different ldap servers, the following changes will be applied to cloudplugins.properties:

com.openexchange.cloudplugins.ldapurl will be renamed to com.openexchange.cloudplugins.read.ldapurl
com.openexchange.cloudplugins.admindn will be renamed to com.openexchange.cloudplugins.read.binddn
com.openexchange.cloudplugins.adminsecret will be renamed to com.openexchange.cloudplugins.read.bindpassword

the following new options will be added:

com.openexchange.cloudplugins.write.ldapurl
com.openexchange.cloudplugins.write.binddn
com.openexchange.cloudplugins.write.bindpassword
