Cause:

Problem was produced because Websphere Syncronization process replaced some files to its original versions.
then that files has not the necessary Shared Key, encrypted passwords, ports and configurations needed to work with IDM correctly.
Files wrongly modified were :
/iam_im.ear/workflow.rar/META-INF/ra.xml
/custom/identitymanager/systemWideProperties.properties

Environment:

Identity Manager 12.6 sp8 :
Cluster 2 Linux Server running in Websphere 8.5.5
MSSQL Database

Resolution:

Need to replace the original files with the customized ones from Backup and the environment started again.

1. From /iam_im.ear/workflow.rar/META-INF/ra.xml
check for the correct values on the Parameters:
UserName
Password

2. From /custom/identitymanager/systemWideProperties.properties , check the correct IMeTASharedSecret value
#This file contains installation specific properties for CA Identity Manager
# Shared secret for the Provisioning server callback
# Note: this used to be in web.xml earlier.
IMeTASharedSecret=
