When configuring an LDAP data store in PingAM, the LDAP Users Search Attribute specifies the attribute in user entries that contains the login ID (e.g., uid, cn, or sAMAccountName). PingAM uses this attribute to search the directory and locate the correct user profile during the authentication process. Changing this value allows an administrator to adapt to different LDAP schemas where the username is stored in a different attribute.

B. LDAP Users Index Attribute is not a standard configuration term; indexing is a backend LDAP performance feature, not a search attribute setting in AM.

C. LDAP Users Bind Attribute is not a setting; the Bind DN is a full distinguished name, not a single attribute used for searching for users.

D. LDAP Users Find Attribute is not the correct name for the property in the PingAM data store configuration UI or its underlying properties.

1. Ping Identity, Access Management Documentation, "Configuring an LDAP data store", Section: "User Configuration". The documentation explicitly lists the field "LDAP Users Search Attribute" and describes it as "The attribute on user entries that contains the user's login ID."

2. Ping Identity, Access Management Documentation, "Create and configure data stores", Section: "LDAPv3 data store properties". This section details the properties for LDAP data stores, where the user search attribute is a key configurable element for defining how user identities are located.
