Class to get the user attributes by username instead of userkey

[yogesh2]

com.saviynt.ecm.identitywarehouse.domain.Users.get("<userkey>")?.customproperty31

above class can fetch the user properties in connection jsons from userkey, is there a way to get the user attributes by username?

somthing like this :

com.saviynt.ecm.identitywarehouse.domain.Users.findByUsername("testuser")?.customproperty31

${com.saviynt.ecm.identitywarehouse.domain.Users.get(user?.manager)?.username}

I dont want to get the manager's attributes.

I am trying to get the customproperty31 of the rank1 owner of the entitlement (not from the role object), and I can get the owner's username like this:

entitlementValuesObj.ownerRank1[0]

but this doesn't work:
entitlementValuesObj.ownerRank1[0].customproperty31

Hence I posted this question.

I am using this in createUpdateMappings json and here is the full json, I am trying to set the managedBy attribute of the group in AD: 

	"cn": "${role?.customproperty27}",
	"objectCategory": "CN=Group,CN=Schema,CN=Configuration,DC=rootq,DC=com",
	"displayName": "${role?.displayname}",
	"sAMAccountName": "${role?.customproperty27}",
	"description": "${role?.description}",
	"extensionAttribute13": "${if(role?.customproperty21?.equals('Security')) {''} else {'MailEnabled'}}",
	"objectClass": "group",
	"name": "${role?.customproperty27}",
	"groupType": "${role?.customproperty21 == 'Mail Enabled Security Group' && role?.customproperty22 == 'Universal'?'-2147483640':role?.customproperty21 == 'Security' && role?.customproperty22 == 'Global'?'-2147483646':role?.customproperty21=='Security'&&role?.customproperty22=='Universal'?'-2147483640' : role?.customproperty21== 'Security'&&role?.customproperty22=='Domain Local'?'-2147483644':role?.customproperty21=='Distribution'&&role?.customproperty22=='Global'?'2':role?.customproperty21=='Distribution'&&role?.customproperty22=='Universal'?'8':role?.customproperty21=='Distribution'&& role?.customproperty22=='Domain Local'?'4':''}",
	"managedBy": "${entitlementValuesObj.ownerRank1[0].customproperty31}"

entitlementValuesObj is entitlement_values object
