Hi,
I'm using sybase ASE 12.0 and I have trying to add a new login to master db with no luck.
I keep getting the following message :

Ad-hoc updates to system catalogs not enabled. A user with System Security Officer (SSO) role must reconfigure system to allow this.
Invalid user specified, password left unchanged.
Error: Unable to set the Password.Ad-hoc updates to system catalogs not enabled. A user with System Security Office (SSO) role must reconfigure system to allow this.

------------------------------------------------------
I have already tried to change the Allow updates flag in sp_configure once again with no success.

Help and new ideas will be much appreciated.
thanks.
izik.
