I seem to have this, so when ever I join io's server he hasta remake me an admin, I was wondering if there is any way to get around this?

You could ask him to give you the admin password.

He should be able to specify this in soldat.ini

When you have this password, you will become admin when doing /adminlog password

Damn, he wont give it out understandibly for security reasons or sumthing, but is there no other way?

no, there's no other way
