Possible bug in USC->AD->USC sync

when adding a group into the USC front end the S4 connector reports the following:

15.11.2022 16:56:05.677 LDAP        (PROCESS): sync UCS > AD: [         group] [       add] 'cn=Sware-Deploy-Lib_01,cn=groups,DC=gp01,DC=org,DC=blown-up,DC=com'
15.11.2022 16:56:06.721 LDAP        (PROCESS): sync AD > UCS: [         group] [    modify] 'cn=sware-deploy-lib_01,cn=groups,dc=gp01,dc=org,dc=blown-up,dc=com'
15.11.2022 16:56:12.786 LDAP        (PROCESS): sync UCS > AD: [         group] [    modify] 'cn=sware-deploy-lib_01,cn=groups,DC=gp01,DC=org,DC=blown-up,DC=com'

now there is clearly showing a case change in the S4 connector log:
so:

  1. is there a case change?
    if so, then S4 should NOT be showing mixed case in the log
  2. if there is NOT a case change
    if so, then S4 should NOT be showing mixed case in the log

if there is a case change then there should be some sort of warning, or the front end should not allow mixed case
