Issue with enrollment some users

Issue with enrollment some users

I  enroll users by external data source but there are some users that when they try change their passwords they get a message indicating that they aren't enrollment. ¿Are there any solution?

I obtain the next error in the serverout0 log:

AuditType : adssp.common.text.reset_pwd ErrorMessage : adssp.reset_unlock.accounts.not_reg_security_qa
