Get custom attribute from LDAP and map into keycloak

Question

we are using synchronize function to get all users from LDAP into keycloak. I want to get custom attribute "User logon name" which is available in LDAP. mapper setting which is already done is getting username, first name, last name, mail. how do i change mapper setting to get "User logon name" from LDAP and save it into username field of keycloak.? i have performed following steps but no luck:

1. changed mapper "LDAP attribute = "User logon name"
2. synchronize all users

any guideline would be appreciated.

From what I understand you want to map a field called "User logon name" from LDAP into a field called username in Keycloak. Try the following:

• Go to Realm where the LDAP is configured;
• Go to User Federation;
• Select the LDAP in question;
• In the Setting tab set the field "Username LDAP Attribute" to "User logon name";
• Click [Save];
• The switch the tab to Mappers;
• Select username;
• edit "LDAP Attribute" to "User logon name"
• Click [Save]; and tried it out.
