User synchronization
The synchronization of the user environment consists of the following three sub tasks after completing
the SAP installation:
Synchronize the user and group ids.
Copy home directory to all the secondary nodes.
In the home directory, adap the filenames containing hostnames.
NOTE: The user environment necessary to run the SAP instances and database instances
must be identical on each cluster node.
To be independent of external services to the cluster like DNS or LDAP, local authorization (for
example, /etc/passwd, /etc/shadow, and /etc/group) is recommended for users and
group information. The SAP and database administrators of the various SAP and DB instances
require the entries listed in Table 19 (page 61) table. The database specific user and groups exist
only if SAP is installed with the corresponding database.
