Looking for suggestion on authentication method for UNIX/Windows

Hello,

We have mid level infrastructure of all on-premises servers. All windows servers are getting authenticated by Microsoft Active Directory Services, half Unix (Solaris+Linux) servers are getting authentication by NIS and other half by LDAP.

We have plans to migrate from NIS to LDAP, so going forward it will all LDAP and Microsoft AD.
Recently we started looking into hosting our few servers on AWS and that made us looking into different prospective.

We are not going to build new/another AD on AWS, but we will use our on-primises directory services for authentication.
Will it be a good approch to integrate LDAP with AD, so that single sign-on can be achieved ?
Or most people will prefer to keep UNIX authentication by LDAP and Windows authentication by Microsoft AD ?
Should I consider any pros or cons with either of these solutions ?
As of now, we are planning to put dashboard application on AWS with two tomcat (web servers) servers, two DB servers. But going forward, this environment will grow with further migrations.

I understand that it is not break-fix question and it is more of consulting question. People who have knowlegde of similar kind of setup, can give me some idea.

I want suggestions from you guys, what can be best possible ways to achieve our goal. I can research in details, but I am looking for high level plan.

If this is not related to correct forum, please move it to appropriate place.

Regards

NAME

       ad - Active Directory as a naming repository

DESCRIPTION

       Solaris clients can obtain naming information from Active Directory (AD) servers.

       The  Solaris  system  must first join an AD domain and then add the ad keyword to the appropriate entries in the nsswitch.conf(4) file. The
       Solaris system joins the AD domain by using the	kclient(1M) utility. The AD name service only supports the naming databases for passwd and
       group.

       Windows	users  are not able to log in. The user_attr(4) database has no entries for Windows users, and the passwd(1) command does not sup-
       port the synchronization of user passwords with AD.

       The Solaris AD client uses auto-discovery techniques to find AD directory servers, such as domain controllers and global  catalog  servers.
       The  client  also  uses	the  LDAP  v3 protocol to access naming information from AD servers. The AD server schema requires no modification
       because the AD client works with native AD schema. The Solaris AD client uses the idmap(1M) service to map between Windows security identi-
       fiers (SIDs) and Solaris user identifiers (UIDs) and group identifiers (GIDs). User names and group names are taken from the sAMAccountName
       attribute of the AD user and group objects and then tagged with the domain where the objects reside. The domain name is separated from  the
       user name or group name by the @ character.

       The  client  uses  the  SASL/GSSAPI/KRB5  security  model. The kclient utility is used to join the client to AD. During the join operation,
       kclient configures Kerberos v5 on the client. See kclient(1M).

FILES

       /etc/nsswitch.conf      Configuration file for the name-service switch.

       /etc/nsswitch.ad        Sample configuration file for the name-service switch configured with ad, dns and files.

       /usr/lib/nss_ad.so.1    Name service switch module for AD.
