LDAP-UX Integration B.04.15 Release Notes

Limitations in NIS/LDAP Gateway
The following are limitations in this version of the NIS/LDAP Gateway.
• Crypt Passwords
The NIS/LDAP Gateway product requires that user passwords be stored in the directory
server in the same format as stored in an /etc/passwd file. This is known as “Unix Crypt”
format. If your directory server does not understand the {crypt} data type, you can still use
the NIS/LDAP Gateway server. However, these users will not be able to authenticate to the
directory server. One side effect is that users will not be able to change their own passwords
(although a directory administrator could accomplish this on a user’s behalf.) Also, other
LDAP enabled applications may not work correctly.
• Modifying Data in the Directory
You cannot use the chfn(1) and chsh(1) and passwd(1) commands to modify data in the
directory.
• NIS and NIS/LDAP Gateway
You cannot run an NIS server (ypserv) and an NIS/LDAP Gateway server (ypldapd)
simultaneously on the same system.
• Shadow Passwords Not Supported
You must set the hide_passwords parameter to “no” in the ypldapd.conf file because
shadow passwords are not supported. See Installing and Administering NIS/LDAP Gateway
for details.
• Use Preloaded Maps instead of ypall_caching
You should use the preload_maps parameter to preload maps into the cache instead of
ypall_caching. Use of ypall_caching can cause a performance bottleneck in the
ypldapd server. For more information, see “Caching” in Installing and Administering NIS/LDAP
Gateway.
