User granted them self groups

[klutch2013]

A user logged into my server for the first time, and granted himself 3 groups:

2012-03-23 18:56:40.079963 | 49| client (id:32230) was added to servergroup 'Donator'(id:1881) by client 'Paul'(id:32230)
2012-03-23 18:56:44.409251 | 49| client (id:32230) was added to servergroup 'Clan Members'(id:724) by client 'Paul'(id:32230)
2012-03-23 18:56:46.854646 | 49| client (id:32230) was added to servergroup 'Approved!'(id:885) by client 'Paul'(id:32230)

i checked their permissions and he had no extra permissions, i also checked the guest permissions, and he logged in as a guest and i checked the guest permissions and that group didn't have permissions to grant themselves groups. so can someone explain how this happened?

Can you post permissions overview, for Default server group.
Find a user who is in this group. Right click on his name ... Permissions > Permissions Overview > Export as PDF .... and post this file here.

You must set in the "Guest" server groups:
Group Member Add Power value = -1
Group Member Remove Power value = -1

[klutch2013]

ok, i did that what about the "Needed Group Member Add Power" should that also be -1? and same for "Needed Group Member Remove Power"

No, don't change needed permissions.
Maybe is helpful read this guide: http://media.teamspeak.com/ts3_liter...ns%20Guide.txt

No need to set any "member_power" values on groups or clients that dont need them.
Instead set "i_group_needed_member_add_power" and "i_group_needed_member_remove_power" values on groups to prevent privilege elevation.
