Reproduced on version 3.0.14a. How to reproduce: Open NT User/Group Manager and try to add an user to an group. System environment is an system that has all users and groups (except for root and demon users/groups) stored in LDAP Database for domain wide login. The System is an x86 1ghz with 512MB Ram running kernel 2.6.12.4 (selfcompiled from vanilla source). Log with loglevel 10 will get attached. I added this bug before to https://bugzilla.samba.org/show_bug.cgi?id=281 because the error message seemed to be the same, but Gerald told me that it is a new one. I'm still not sure if this rather belongs to Domain Control or User/Group Accounts... I stick to the latter one.

Thanks CHristian. Any chance of testing 3.0.20 to see if the bug still exists?

Should be fixed by8 this patch. Will check it into the SAMBA_3_0 after some more review. Thanks to John Janosik <jpjanosi@us.ibm.com> for pointing out the error.
