Figured it out - it was an issue with the space behind the comma.

So "SSL_CLIENT_I_DN: C=DE, O=Test-Organisation, OU=Test-OU, CN=Test-CN" was split to an array but, with leading spaces: 

"C|AT"  
" O|Test...."  
" OU|Test..."  
etc.

So in this part:

foreach {part myvar} {
     {C}       {SSL_CLIENT_I_DN_C}
     {CN}      {SSL_CLIENT_I_DN_CN}
     {O}       {SSL_CLIENT_I_DN_O}
     {OU}      {SSL_CLIENT_I_DN_OU}

the only line that was readable from the array was C, all other didn't match because of the space.
