Usando awk fica facil
        awk -F: ' BEGIN {
                previous = "";
                tmp = ""
        }
        tmp == "" {
                tmp = $0;
                previous = $1;
                next;
        }
        previous != $1 {
                print tmp;
                tmp = $0;
                previous = $1;
                next
        }
        {
                tmp = tmp ", " $2
        }
        END {
                print tmp
        } ' saida.txt


No seu exemplo:

[begnini@coke tmp]$ cat a.txt
dph467:testando1
dph467:lalalarerera
dph467:kloiad
wjn028:mhaqj
wjn028:wjaksd
wjn028:tesada
wjn028:223122
[begnini@coke tmp]$ awk -F: ' BEGIN { previous = ""; tmp = "" } tmp == ""  
{ tmp = $0; previous = $1; next; } previous != $1 { print tmp; tmp = $0;  
previous = $1; next } { tmp = tmp ", " $2 } END { print tmp } ' a.txt
dph467:testando1, lalalarerera, kloiad
wjn028:mhaqj, wjaksd, tesada, 223122
[begnini@coke tmp]$
