Wi-Fi Network setting

Hi
I am testing wifi network setting, about iOS...I find 2 problem.
[iOS Wi-Fi]
1. I set iOS wifi network, and run [assign to LDAP Groups/Folders], select one group which include one user.
2. After I completed wifi setting, I return to [Corporate Resources] on user's profile for checking, but I find it show [No Wi-Fi Networks assign to xxx].==>the [assign to LDAP /Folders] setting seem work fail.
3. I need perform [Assign New Wi-Fi Network] from user's profile, the setting work fine.

[Andriod's Wi-Fi]
1. the condition is defferent with iOS, why set same Wi-Fi network setting, the Andriod is complex!! on iOS I only select [security type];but Andriod I need set much sepecial security setting (I just set a WEP type , which document could teach me STD setting??)
2. but when I set the the andriod network, the [assign to LDAP Groups/Folder] work fine....I could see the setting from user's profile although the wifi setting is not I want to set.

[Result]
1. about iOS W-fi , the [Assign LDAP Groups/Folders] work fail
2. the andriod wi-fi setting could provide easily method like iOS Wi-Fi setting ??
