Properties of a user are not deleted by a synch.
Only if it is a synched property from the LDAP Active Directory the value gets overwritten.
Example of a synched property in the ivy.yaml
:
SecuritySystems:
ad:
Provider: "Microsoft Active Directory"
UserAttribute:
# Here you can specify a list of additional LDAP attributes that are imported and available as user properties (IUser.getProperty)
Properties:
# Maps a user property to an LDAP attribute
# In the example below 'phoneNumber' is the name of the user property.
# The value of the property is imported from the LDAP attribute 'phone' of the user.
phoneNumber: phone
