I am setting LDAP in an init.groovy script with

LDAPGroupMembershipStrategy groupMembershipStrategy = (LDAPGroupMembershipStrategy) new FromUserRecordLDAPGroupMembershipStrategy("memberOf");

def ldapRealm = new LDAPSecurityRealm(
server = server,
rootDN = rootDN,
userSearchBase = userSearchBase,
userSearch = userSearch,
groupSearchBase = groupSearchBase,
groupSearchFilter = groupSearchFilter,
groupMembershipFilter = groupMembershipFilter,
managerDN = managerDN,
managerPassword = managerPassword,
inhibitInferRootDN = false,
disableMailAddressResolver = false,
cache = cache,
environmentProperties = environmentProperties,
displayNameAttributeName = displayNameAttributeName,
mailAddressAttributeName = mailAddressAttributeName
);
cijenkins.setSecurityRealm(ldapRealm)
cijenkins.save()

However, the config.xml that is created has

<groupMembershipStrategy class="jenkins.security.plugins.ldap.FromGroupSearchLDAPGroupMembershipStrategy">
<filter>memberOf</filter>
</groupMembershipStrategy>

and I am unable to login unless I manually edit the config.xml to the correct value.
