When ipa trust-add is executed with --range-type ad-trust-posix, the server tries to find the max uidnumber and max gidnumber from AD domain controller. The values are extracted from the entry CN=<domain>,CN=ypservers,CN=ypServ30,CN=RpcServices,CN=System,<AD suffix> in the msSFU30MaxUidNumber and msSFU30MaxGidNumber attributes. msSFU30MaxUidNumber is required but not msSFU30MaxGidNumber. In case msSFU30MaxGidNumber is missing, the code is currently assigning a "None" value and later on evaluates the max between this value and msSFU30MaxUidNumber. The max function cannot compare None and a list of string and triggers an exception. To avoid the exception, assign [b'0'] to max gid if msSFU30MaxGidNumber is missing. This way, the comparison succeeds and max returns the value from msSFU30MaxUidNumber.

FreeIPA Server
FreeIPA allows Linux administrators to centrally manage identity, authentication and access control aspects of Linux and UNIX systems by providing simple to install and use command line and web based management tools.
FreeIPA is built on top of well known Open Source components and standard protocols with a very strong focus on ease of management and automation of installation and configuration tasks.
FreeIPA can seamlessly integrate into an Active Directory environment via cross-realm Kerberos trust or user synchronization.
Benefits
FreeIPA:
- Allows all your users to access all the machines with the same credentials and security settings
- Allows users to access personal files transparently from any machine in an authenticated and secure way
- Uses an advanced grouping mechanism to restrict network access to services and files only to specific users
- Allows central management of security mechanisms like passwords, SSH Public Keys, SUDO rules, Keytabs, Access Control Rules
- Enables delegation of selected administrative tasks to other power users
- Integrates into Active Directory environments
Components
The FreeIPA project provides unified installation and management tools for the following components:
- LDAP Server - based on the 389 project
- KDC - based on MIT Kerberos implementation
- PKI based on Dogtag project
- Samba libraries for Active Directory integration
- DNS Server based on BIND and the Bind-DynDB-LDAP plugin
