Thats not supported and it is highly recommendet to not do this. Plain text passwords in the mysql DB are a securoity nightmare. If you really want to do this, you will have to change the ispconfig sources, especially the form library.
Ok Thankx, Only reason I ask is I am trying to migrate from ISPConfig2 to 3 and the first issue was all the passwords, I now see that with ISPC3 it no longer stored the passwords in the shadow file but in the db. but makeing them clear test, future upgrade will not be a big problem. But I do get your point about security.
There is no problem with the passwords when you migrate from ispconfig 2 to 3 that I'am aware of as they are encrypted with crypt in both versions. So you can copy them from the shadow file of the ispconfig 2 install into the password field of the ispconfig 3 database table.
