## Symptoms

- * After upgrading the GAIA O.S to any latest version.

## Solution

For this option to work, the 2 files are responsible:-  
a. dynamic_id.C   
b. cvpnd.C  
Files Location: /opt/CPshrd-R80.40/conf/  

While upgrading O.S or while changing configuration (Legacy to Unified), files might get overridden or some parameters did not take effect.   
Need to verify if the parameter ":smsMaxResendRetries" exists on both of the files .  

++If the parameter is missing in dynamic_id.C file, please add it manually.   
++The result of the file must be like attached below.

:util_args ("")  
:util_proxy_args ("-x")  
:users_info_list ("/conf/dynamic_id_users_info.lst")  
:challenge_matcher_list ("/conf/dynamic_id_matcher.lst")  
:reuse_matcher_for_resend (true)
