When using the import function can see it displays a user that already exists. We haven't tried importing an existing user.
Release : 6.6, 6.7
Component : CA RELEASE AUTOMATION REPOSITORY
In investigation it was found that this is an old/migrated users from old RA version. On validating the user entry in DB it was found that the user has LDAP_DN=NULL/EMPTY. The RA validate the LDAP_DN to determine if the user is imported from LDAP or not. It matches the same for specified user filter in DB to determine if the "user can't be re-imported" or can be "re-imported".
Impact
1: There is no problem in terms of functionality w.r.t. user showing re-import message as the only one record existing in DB. User are uniquely identified by there username.
Workaround (In case if you want to get rid of message)
1: Identify the user detail from table "Select * from users where username like '%USER_NAME%'. Please change USER_NAME by respective username in your environment.
2: Either of the below mentioned workaround can be applied
2.1: Remove the user and re-import the user again from LDAP/AD
2.2: Identify a user with correct behavior and check the LDAP_DN for that user and modify the problematic user LDAP_DN in accordance to correct user.
3: Try to search for the user and the message "already imported" should appear.
